Latches, Strikes, & Parts
Lock parts are the replacement latches, strike plates, levers, spindles and deadbolt assemblies that keep a commercial door working without replacing the whole lockset. They are for locksmiths, maintenance teams and facility managers matching a part to an existing lock. Start with the Schlage 13-248 spring latch, the Schlage 14-047 deadlatch, the Don-Jo EL-125 extended lip strike for forced entry resistance, or the Schlage 10-025 ANSI strike.

Door Latch Parts and Latch Bolt Replacement
A door latch is the bolt and faceplate that catches in the strike, and replacing it is often cheaper than replacing the lockset. The main parts are the latch bolt, the faceplate, and, on a deadlatch, a plunger that locks the bolt so it cannot be pushed in. Spring latches, such as the Schlage 13-248 spring latch, have no deadlocking plunger. Deadlatches, such as the Schlage 14-047 deadlatch, resist loiding and are common on exterior and storeroom doors. Match the backset (2-3/8, 2-3/4 and 3-3/4 inch are all listed), the face size (1-1/8 by 2-1/4 inch is common) and the series.
Strike Plates: ANSI, T-Strike and Extended Lip
A strike plate receives the latch, and the right one depends on the frame prep and the latch face. An ANSI strike measures 1-1/4 by 4-7/8 inches and fits standard prepped frames, like the Schlage 10-025 ANSI strike. T-strikes fit narrower frames, full lip strikes wrap the frame edge, and extended lip versions such as the Don-Jo EL-125 extended lip strike span a bigger gap between door and frame. Radius corner strikes match rounded faceplates, square corner strikes match square ones. The commercial door strike plates guide compares them.
Security Strikes and Reinforcement
A security strike is a heavier plate that spreads force across the frame instead of a thin standard plate. The Don-Jo 2-SDS-8 and the AST series are examples. They add strength at the point where a door is most often forced. Pair a reinforced strike with long screws into the framing and check that the door still latches without binding.
Lever, Spindle and Deadbolt Replacement Parts
Many repairs need only a lever, spindle or deadbolt assembly. Schlage ND replacement levers come in open, closed, cylinder prep and SFIC versions. Some are marked ND Series (Before February 2017), so check the date range before ordering. Falcon T and B Series levers and the 030733 spindle cover Falcon locks, and the Accentra (Yale) D34 deadbolt assembly fits D100 and D200 series with a 2-3/4 inch backset. When a lock is worn throughout, see the repair vs replace guide.
How to Match a Part to Your Lock
Match by brand and model first, then measure what you cannot read. Find the model on the lock edge or latch, then measure backset (door edge to center of the knob hole), latch face size, and strike dimensions. Note the handing, finish and the core prep for levers. If the model is worn off, send a photo of the latch, strike and trim and we will identify the part.

Frequently Asked Questions
What is the difference between a standard strike plate and a security strike plate?
A standard strike plate is a thin plate that only receives the latch. A security strike is a heavier plate that spreads force across more of the frame and is meant to reinforce the area. Don-Jo security strikes such as the 2-SDS-8 and AST series are examples. Fit depends on the frame prep.
How do I choose the correct extended-lip strike for my door?
Measure the gap between the door edge and the frame, then match the lip length, strike height and corner shape to your latch. Extended lip strikes are made for frames where the standard lip is too short to catch the latch. Check the listing for the dimensions before you order.
Can I use a Don-Jo strike plate with a Yale (Accentra) lockset?
Often yes. Strike fit depends on the latch face size, backset and frame prep, not the brand. An ANSI strike is 1-1/4 by 4-7/8 inches, so measure your existing strike and latch face and compare against the listing. If the dimensions match, the strike will work with the latch.
When should I replace a latch bolt assembly instead of the entire lockset?
Replace the latch when the lock body is sound and only the bolt is worn, sticking or broken. Replace the lockset if the chassis, lever springs and cylinder are all worn, or if the model is discontinued. A latch is a quick fix, and it keeps your keying and trim unchanged.
What lock parts are needed to reinforce a door frame against forced entry?
Start with a security strike or extended lip strike and long screws that reach the framing. A deadbolt assembly adds a second bolt, and latch guards can block prying. Hollow metal frames also benefit from filling the strike cavity. Choose parts rated for the door and frame you actually have.
Do you carry fire-rated latch and strike components?
Fire rated openings need listed hardware that latches positively, under NFPA 80, and the door and frame label sets the requirement. Check each product listing for fire rating information and call us with the door label details; we will confirm a compatible latch and strike before you order.
What is the difference between a spring latch and a deadlatch?
A spring latch has a spring loaded bolt that retracts with the lever and can be pushed back with a tool. A deadlatch adds a plunger that locks the bolt when the door closes, so it cannot be pushed in. Deadlatches suit exterior and storeroom doors; spring latches suit passage doors.
How do I measure the backset for a replacement latch?
Measure from the edge of the door to the center of the lock hole, or the center of the cross bore. The common sizes are 2-3/8 and 2-3/4 inches, and 3-3/4 inches is also listed. Get the backset right or the latch will not line up with the strike or the lever.
