Quick Verdict

Both families fit the same 1-1/4 in. x 4-7/8 in. aluminum jamb cutout and accept Adams Rite 4500, 4700 or 4900 deadlatches and cylindrical latches with 1/2 in. to 5/8 in. latchbolt projection. Choose the 7400 Ultraline (about $208 at NLS) for exterior storefronts: it holds over 1,500 lbs fail secure, releases under up to 25 lbs of door preload, and its jaw inserts adjust for door and frame preload. Choose the 7100 (about $153 at NLS) for interior or low-preload doors, or when the controller supplies AC: the 7100 family runs 12, 16 or 24 V AC or DC, while the 7400 runs 12/24 VDC (16 VDC with the VA7400-16 adapter). Hollow metal or wood jambs take the 7140 or 7440. Fire-rated hollow metal openings take the 7270, fail secure only.

How do the 7100 family and 7400 Ultraline compare on faceplate, jamb and power?

The two families share the strike geometry that matters to a storefront retrofit: same faceplate sizes, same latchbolt projection range, same deadlatch compatibility. The differences are in the mechanism and the power.

7100 family. UL 1034 burglary-resistant and UL 294 listed. Available in 12, 16 or 24 V AC or DC; DC continuous units are silent, AC intermittent units buzz on operation. Current draw is 0.33 A at 12 VDC and 0.17 A at 24 VDC. Fail safe or fail secure is field selectable at installation, but the AC intermittent solenoid must not be used continuously in either mode. Case is 1 in. x 3-3/8 in. x 1-5/8 in. deep; strike opening 5/8 in. x 1-7/16 in. x 1/2 in. deep with a stainless keeper.

7400 Ultraline. Non-handed, ultra-compact body with adjustable stainless keepers, over 1,500 lbs of holding force in fail secure mode, field selectable fail safe or fail secure. A single solenoid runs 12/24 VDC, field selectable; 16 VDC requires the VA7400-16 adapter. The key storefront spec: it opens electrically under 25 lbs of preload, the pressure from air conditioning systems, warped doors or misaligned hardware "which can disable common electric strikes." Jaw inserts of various sizes compensate for door and frame preload.

7270	1-1/4 x 4-7/8 in., flat, square corners	Hollow metal	UL 10C, 3 hour single door, fail secure only	Adams Rite 7270

Faceplate length is the retrofit shortcut: measure the existing strike cutout and match 4-7/8 in., 6-7/8 in., 7-15/16 in. or 10-1/4 in. before anything else. Faceplate shape and corner conventions are covered in electric strike faceplates: ANSI vs ASA.

What to order: the 7400 Ultraline for exterior aluminum storefronts, the 7100 for interior or AC-powered systems.

Aluminum jamb vs hollow metal or wood jamb: 7130 and 7101 vs 7140?

Corners tell you the jamb. Adams Rite uses radius corners on its aluminum jamb faceplates (7100, 7130, 7400, 7430) and square corners on its hollow metal or wood versions (7140, 7440, 7270). Radiused faceplates (7101, 7131, 7401) are a different thing: the face is curved "to match nose on inactive leaf in a pair of narrow stile doors." Order a radiused face only when the strike goes in the inactive leaf of a storefront pair.

Practical sorting:

• Single aluminum storefront door, 4-7/8 in. cutout: 7100 or 7400.
• Single aluminum door, 6-7/8 in. cutout: 7130 or 7430.
• Pair of narrow stile doors, strike in the inactive leaf: 7101 (4-7/8 in.) or 7131 (6-7/8 in.), or Ultraline 7401.
• Hollow metal or wood frame with an Adams Rite deadlatch door: 7140 or 7440.
• Long cutout from an older strike, any jamb material: 7110 (7-15/16 in.) or Ultraline 7411 (10-1/4 in.).
• Mortise or cylindrical lock with up to 3/4 in. latchbolt in aluminum, no deadbolt: 7160, which has a 1-7/8 in. deep case.

Both 7100 and 7140 list "lip extension 1-1/16 in. or less." If the door sits farther from the jamb face than that, stop and measure before ordering.

What to order: the 7140 for hollow metal or wood frames; aluminum radius-corner models from the electric strikes category for storefront frames.

What do you use on a fire-rated opening: the 7270?

Narrow stile aluminum storefronts are rarely labeled fire doors, but Adams Rite deadlatch hardware shows up on hollow metal openings that are. For those, the 7270 is the listed choice: hollow metal jamb, 1-1/4 x 4-7/8 in. square corner faceplate, for mortise or cylindrical locksets with up to 3/4 in. latchbolt projection without a deadbolt. It is UL 10C fire rated for a 3-hour single door in fail secure mode only, CAN/ULC-S104 conformant, and ships assembled fail secure (locked when unpowered). Current draw matches the 7100 family at 0.33 A at 12 VDC and 0.17 A at 24 VDC. It is about $362 at NLS.

Never field-convert a fire door strike to fail safe: on a labeled opening the latch must stay engaged in a fire. The authority having jurisdiction (AHJ) and local code govern any electrified hardware on a fire-rated or egress door, and installation belongs to a qualified technician.

What to order: the Adams Rite 7270 for labeled hollow metal frames.

How do you match the strike to the deadlatch (4900, 4500, 4300)?

Every 7100 and 7400 listing names the same locks: Adams Rite 4500, 4700 (discontinued) or 4900 deadlatches, or cylindrical locksets with 1/2 in. to 5/8 in. latchbolt projection. The strike releases the keeper, so the deadlatch bolt pushes out without operating the latch, and the outside trim never has to change.

Two traps:

1. The 4300 is an electrified deadlatch. It retracts its own bolt, so it does not need an electric strike. Its jamb takes a mechanical strike: Adams Rite lists the 4901 and 4902 deadlatch strikes for 4300 electrified deadlatches as well as the 4510, 4530 and 4900 series. Ordering an electric strike for a 4300 door doubles the cost and the wiring.
2. 4500 vs 4900 bolt width. The 4901/4902 strikes accept the 1/2 in. bolt of the 4500 and 4700 and the 5/8 in. bolt of the 4900 by removing a snap-in nylon insert. Confirm which deadlatch is in the door before touching the jamb.

The deadlatch decision itself is in our sibling guide, Adams Rite 4900 vs 4500 deadlatch.

What to order: a 7100 or 7400 for a 4500 or 4900 door; a mechanical 4901 or 4902 strike if the door carries a 4300.

What else goes on a keyless storefront retrofit order?

The strike is one line. A working opening needs power, a credential, a legal way out and a status signal.

Retrofit component	Purpose	Example
Electric strike	Releases the deadlatch bolt	Adams Rite 7400
Power supply	Regulated 12 or 24 VDC to strike and reader	Sized per access control power supply guide
Reader or keypad	Credential on the outside	Controller-matched reader or standalone keypad
Request to exit	Tells the panel exit is intentional, prevents forced-door alarms	Chosen per request-to-exit guide
Door position switch	Reports open or closed for held and forced alarms	See door position switches: concealed vs surface
Door cord or transfer	Only if the door carries powered hardware	Not needed for a strike-only retrofit

A strike lives in the frame, so a strike-only retrofit needs no wire across the hinge, which is the main reason it is the lowest-cost way to make an existing storefront keyless. Run the strike on DC: the 7400 is DC only, and the 7100 listing warns that AC intermittent units must not be energized continuously. Fail secure keeps the storefront locked on power loss while the inside paddle or thumbturn still lets people out; confirm that egress arrangement with the AHJ.

What to order: the strike from electric strikes, plus supply, reader, REX and DPS on the same cart.

Which fields go on the order?

• Family: 7100 (AC or DC, standard) or 7400 Ultraline (DC, preload rated).
• Faceplate length: 4-7/8, 6-7/8, 7-15/16 or 10-1/4 in.
• Faceplate shape: flat radius corners (aluminum), flat square corners (hollow metal or wood), radiused (inactive leaf).
• Voltage: 12, 16 or 24; AC or DC for the 7100; VA7400-16 adapter if a 7400 must run on 16 VDC.
• Function: fail secure or fail safe, set in the field (7270 ships fail secure only).
• Finish: match the storefront; search terms like 7400-628, 7400-313 and 7400-335 refer to finish codes on the same strike.
• Deadlatch in the door: 4500, 4900 or 4300.

Common mistakes

1. Ordering a 7100 for an exterior storefront with air pressure or warp preload. The 7400 is the model rated to release under 25 lbs of preload.
2. Running a 7100 AC unit continuously as fail safe. The listing forbids continuous use of the AC intermittent solenoid.
3. Ordering a radiused faceplate (7101, 7131, 7401) for a single door.
4. Buying an electric strike for a door with a 4300 electrified deadlatch.
5. Ordering by part number memory instead of measuring the 4-7/8 in. vs 6-7/8 in. cutout.
6. Using a 7400 on a labeled fire door instead of the 7270.
7. Forgetting the 16 VDC adapter when a 7400 goes on a 16 V system.

FAQ

What is the difference between the Adams Rite 7100 and 7400? Both fit 1-1/4 x 4-7/8 in. aluminum jamb cutouts and work with 4500, 4700 and 4900 deadlatches. The 7400 Ultraline adds over 1,500 lbs fail secure holding force, release under 25 lbs of preload and adjustable keepers, and runs 12/24 VDC. The 7100 runs 12, 16 or 24 V AC or DC.

Is the Adams Rite 7400 fail safe or fail secure? It is field selectable for either. Fail secure is the common storefront setting because the door stays locked on power loss while free egress stays with the inside trim; the AHJ confirms the arrangement.

What is the Adams Rite 7130 electric strike? The 7130 is the 7100 family strike with a 1-1/4 x 6-7/8 in. flat, radius corner faceplate for aluminum jambs. Its Ultraline equivalent is the 7430.

Which Adams Rite electric strike fits a hollow metal jamb? The 7140 (7100 family) and 7440 (Ultraline) use square corner faceplates for hollow metal or wood jambs. On a labeled fire door, use the 7270.
