Top 10 Exit Strike Plates for Maximum Security: Commercial Door Protection
Posted by National Lock Supply on Dec 4th 2025
Exit strike plates represent the last line of defense in commercial door security systems, anchoring latch bolts and deadbolts into the door frame with enough strength to resist forced entry, abuse, and millions of operational cycles. While panic bars, exit devices, and high-security locks receive most attention during security planning, the strike plate determines whether that expensive hardware actually prevents unauthorized entry or fails during the first determined attack. Facility managers and security professionals understand that even the most sophisticated locking system is only as strong as its weakest component, and in many installations, that weak point is an undersized, poorly installed, or incorrectly specified strike plate.
This guide identifies the top commercial strike plates based on material strength, mounting specifications, security features, code compliance, and field-proven resistance to forced entry attempts. We've evaluated strikes across critical criteria: metal gauge and composition, fastener specifications and penetration depth, lip design and latch engagement geometry, fire rating certifications, and documented performance in high-security and institutional environments. Whether specifying hardware for new construction, upgrading failing strikes in existing buildings, or addressing security vulnerabilities identified during assessments, these products represent the industry's strongest solutions for protecting commercial door openings.
1. Electric Strikes: The Access Control Foundation
Remote Release with Security-Grade Construction
Electric strikes revolutionize commercial access control by providing remote unlocking capability while maintaining mechanical security when power fails. Unlike magnetic locks that fail-open during power loss, quality electric strikes fail-secure, keeping doors locked until intentionally released. The best models combine heavy-duty stainless steel construction, Grade 1 ANSI/BHMA ratings, and UL 1034 listings verifying performance under standardized testing that simulates years of high-frequency use and forced entry attempts.
Installation requires careful attention to frame preparation and electrical integration. The strike mortise must match device dimensions precisely; oversized pockets weaken frame integrity, while undersized mortises prevent proper strike seating. Low-voltage wiring (12-24VDC typical) must follow code requirements for access control circuits, with proper circuit protection and compliance with fire alarm integration standards where required. Frame reinforcement often exceeds standard strike requirements due to the concentrated loads that electric strike mechanisms generate.
Leading manufacturers offer cylindrical electric strikes for knob and lever locks, mortise electric strikes for institutional locksets, and rim exit electric strikes for panic hardware. Adjustable keeper positions compensate for minor frame-to-lock misalignment, while fail-secure and fail-safe options address different security requirements. Fail-secure maintains a locked state during power failure, appropriate for perimeter doors and high-security areas. Fail-safe releases during power loss, required for life-safety egress paths and fire alarm integration.
2. Heavy-Duty Stainless Steel Strikes: Corrosion-Resistant Strength
Marine-Grade Performance for Demanding Environments
Stainless steel strikes deliver superior corrosion resistance in coastal installations, commercial kitchens, natatoriums, car washes, and other high-moisture environments where standard steel strikes rust within months. Type 304 stainless provides adequate corrosion resistance for most commercial applications, while Type 316 marine-grade stainless handles extreme exposure, including salt spray, chemical environments, and direct weather contact. The stainless steel strike plate costs 150-200% more than equivalent steel versions, but eliminates replacement costs and operational disruptions from corrosion-induced failures.
Gauge specifications determine strength; 18-gauge (.048") suits light commercial applications, 14-gauge (.075") handles standard commercial doors, while 12-gauge (.104") or heavier provides institutional-grade strength for high-security and abuse-resistant installations. Thicker material resists deflection under impact, prevents spreading that allows latch bypass, and provides adequate material for deep fastener penetration without breakthrough.
Mounting requires stainless steel fasteners to prevent galvanic corrosion between dissimilar metals. Using standard steel screws in stainless steel strikes creates electrochemical reactions that rapidly corrode fasteners, weakening the installation. Specify complete stainless hardware packages, including strikes, fasteners, and any reinforcement plates, to ensure compatible materials throughout.
3. Fire-Rated Strike Plates: Life Safety Compliance
UL-Listed for Fire Door Assemblies
Fire-rated strikes carry UL or cUL listings certifying performance in fire door assemblies tested to UL 10C standards. These strikes must maintain latching function through the rated duration (90 minutes, 3 hours, etc.) under temperature exposure and positive pressure testing simulating actual fire conditions. Using non-rated strikes on fire doors voids the complete assembly certification, creating code violations that shut down buildings during inspections and potentially catastrophic consequences during actual fires.
The strike label verifies, fire marshals check these during routine inspections. Missing or painted-over labels trigger violations requiring immediate correction. Maintain strike packaging and documentation proving UL compliance for building records supporting future inspections. Some jurisdictions require permanent installation records documenting all fire-rated components by location, installation date, and certification numbers.
Fire-rated strikes often require specific installation parameters beyond standard commercial practice. Fastener type, count, and penetration depth may be specified in the listing; deviating from these requirements voids certification. Frame reinforcement, when required, must meet listing specifications. Keep manufacturer installation instructions on file, proving compliance with all listing requirements.
4. Wide Lip Strikes: Maximum Latch Engagement
Extended Protection Against Spreading Attacks
Wide lip strike plates extend the latch engagement area, providing resistance against frame spreading attacks where attackers pry the door and frame apart to bypass the latch. Standard strikes offer 1/2" to 5/8" lip depth, adequate for normal commercial use but vulnerable to determined attacks. Security-grade wide lip strikes extend 1-1/4" to 1-1/2" or more, requiring substantially more frame deformation before the latch can slip past the strike lip.
The extended lip demands deeper frame mortising, which can weaken thin-section frames unless properly reinforced. Hollow metal frames need reinforcement plates behind the strike, distributing loads across wider areas. Wood frames benefit from blocking or backing plates, providing solid material for deep mortise cutting. The installation complexity pays dividends in forced entry resistance. Testing shows that wide lip strikes significantly increase the force and time required for successful frame spreading attacks.
Combined with commercial hinges featuring non-removable pins or continuous designs, wide lip strikes create comprehensive door edge security, preventing both hinge-side and latch-side bypass attempts. Specify both components together for openings requiring attack-resistant performance beyond standard commercial security levels.
5. ANSI/BHMA Grade 1 Certified Strikes: Tested Durability
Verified Performance Through Standardized Testing
ANSI/BHMA A156.13 establishes performance standards for strikes, including strength testing, cycle endurance, and operational testing under varied conditions. Grade 1 strikes represent the highest certification level, tested to resist 800 pounds of pull force, 350 pounds of side load, and operational cycling exceeding 500,000 cycles. This testing simulates both security attacks and long-term operational wear in high-traffic commercial installations.
Grade 1 certification costs manufacturers significant testing investment, which is reflected in retail pricing, expecting 30-50% premiums over non-certified equivalents. This premium buys verified performance rather than marketing claims. Independent testing laboratories confirm specifications before issuing certifications, assuring that the strike actually delivers advertised strength and durability.
Institutional specifications often mandate Grade 1 hardware across all commercial door openings. Schools, hospitals, government facilities, and corporate headquarters benefit from standardized performance levels that simplify specification, ensure consistent quality, and reduce maintenance through enhanced durability. The upfront cost premium disappears quickly when compared against replacement costs and operational disruptions from failed lower-grade hardware.
6. Adjustable Strikes: Compensation for Misalignment
Field-Tunable for Optimal Latch Engagement
Door sag, frame settling, and seasonal wood movement create latch-to-strike misalignment that prevents proper latching or forces excessive door pressure during closing. Adjustable strikes incorporate movable keepers or shims, allowing field adjustment to compensate for these alignment variations without strike replacement or frame modification. This feature proves invaluable during building settling periods, seasonal weather changes affecting wood-frame buildings, and renovation projects where existing openings have shifted from original specifications.
The adjustment mechanism varies by design; some use shims behind the keeper plate, others provide slotted mounting allowing strike repositioning, and sophisticated models include micro-adjustment screws enabling precise positioning without loosening mounting fasteners. Adjustment range typically spans 1/8" to 1/4" vertical or horizontal movement, adequate for most alignment corrections while maintaining strike strength.
Installation requires initial positioning at mid-adjustment range, allowing equal correction capacity in either direction. Setting strikes at adjustment limits during installation leaves no margin for future building movement or seasonal changes. Document initial adjustment positions and remaining range for maintenance records supporting future adjustment decisions.
7. Deadbolt Strikes: High-Security Door Protection
Full 1" Throw Engagement for Maximum Strength
Deadbolt strikes accommodate the full 1" throw projection standard commercial deadbolts provide, creating engagement depth that resists prying attacks substantially better than the 1/2" throw standard latch bolts offer. The deeper engagement requires correspondingly deeper frame mortising and longer fasteners penetrating farther into frame material, both factors increasing security while demanding more careful installation.
Security-grade deadbolts strikes often incorporate hardened steel inserts resisting drilling and cutting attacks targeting the bolt/strike interface. Anti-saw pins embedded in the strike face damage saw blades and drill bits, significantly increasing attack difficulty and time. For high-value storage, server rooms, pharmaceutical areas, and other critical security applications, these attack-resistant features justify their premium cost.
Combining deadbolts with separate latchbolts (double-cylinder configurations or interconnected locks) creates two-point locking with strikes at different frame locations. This distributed security prevents the single-point-of-failure vulnerability standard locksets create; attacking either the latch or deadbolt alone won't open the door. Coordinate strike specifications ensuring both provide equivalent security levels.
8. Mortise Lock Strikes: Institutional Standard
Precision Engagement for Commercial Locks
Mortise locks, the standard in institutional and commercial construction, require strikes specifically designed for their keeper geometry and operational characteristics. Unlike cylindrical lock strikes that accommodate round latch bolts, mortise electric strikes work with rectangular deadlatch and deadbolt projections requiring precise keeper cutouts matching exact lock dimensions. The strike must engage both the latch (providing pull resistance) and the dead latch (preventing latch retraction through shimming) simultaneously.
Quality mortise strikes incorporate anti-spread lips, preventing frame deformation that would allow latch bypass. The box strike design, with depth accommodating full bolt projection plus operational clearance, provides engagement volume for the bolt travel during operation. Insufficient depth causes the bolt to bottom in the strike rather than latching fully, creating operational problems and security vulnerabilities.
Fire-rated mortise lock installations require strikes carrying equivalent fire ratings. The complete assembly lock, strike, and any auxiliary hardware must maintain UL listing as a system. Mixing rated and non-rated components voids certifications regardless of individual component quality. Verify complete assembly compatibility before specifying hardware for fire-rated mortise lock installations.
9. Exit Device Strikes: Life Safety Integration
Panic Hardware Security and Egress
Exit device strikes serve the dual requirements of life-safety egress and security, latching panic bars securely while releasing instantly when the touchpad is pressed. Rim exit electric strikes mount on the frame face, accepting the latch projection from surface-mounted panic mechanisms. Vertical rod strikes are installed at the door top and bottom, receiving rods extending from the panic device. Mortise exit device strikes integrate into the frame edge, accommodating mortise-style panic hardware.
UL fire rating requirements for panic exit devices extend to strikes; fire-rated exit devices need strikes carrying equivalent ratings and installed per listing requirements. The strike must maintain latching force through fire exposure, withstanding both thermal effects and the positive pressure testing simulating building pressurization during fires. Non-rated strikes void the complete life-safety assembly certification.
Electric latch retraction options integrate panic hardware with access control systems. The electrified strike retracts mechanically during panic operation (preserving life-safety egress) while also releasing electrically from access control commands. This dual-release capability suits high-security areas requiring controlled entry while maintaining code-compliant emergency egress. Fail-safe operation ensures power loss doesn't prevent egress, critical for life-safety applications.

Selection Criteria for Commercial Strikes
Matching Strike Specifications to Application Requirements
Selecting the optimal strike plate requires a systematic assessment of security requirements, traffic volume, environmental exposure, code compliance mandates, and operational characteristics specific to each opening. Start with lock type: cylindrical electric strikes for knob and lever locks, mortise strikes for institutional locksets, deadbolt strikes for high-security applications, and rim exit strikes for panic hardware. Each requires designs matching their specific keeper geometry and operational forces.
Door weight and closing force affect strike selection. Heavy doors with powerful closers generate impact forces that can deform lightweight strikes, creating alignment problems and premature failure. Match the strike gauge to the door weight and closer force. Light doors with standard closers function with 18-gauge strikes, while heavy institutional doors need 12-gauge or heavier construction, absorbing impact without deformation.
Frame material dictates mounting methodology and reinforcement requirements. Wood frames accept wood screws in solid material, hollow metal frames need machine screws threaded into reinforcement plates or tapped holes, and aluminum frames often require specialized fasteners, accounting for material softness and thermal expansion. Never compromise on fastener specification; they're as critical as strike strength in determining total system security and longevity.
