Corbin Russwin 867F21-630 – Frequently Asked Questions

1) What backset does the Corbin Russwin 867F21 deadlocking latch have?
The 867F21 is a 2-3/4 inch backset latch, which is the standard commercial mortise backset. If the lock case you are rebuilding is prepped at 2-3/8 inches, this latch will not line up with the existing cross bore and spindle location, so confirm the backset off the old case before you order.
2) Will the 867F21 latch fit my existing mortise pocket and faceplate cutout?
It uses a square corner front measuring 1-1/8 inches (29mm) wide. That matches a standard mortise lock edge prep with a square-cut faceplate mortise. If your door edge is routed with radius corners, a square corner front will leave gaps at the corners unless the pocket is squared out with a chisel.
3) What is a deadlocking latch and why would I need one on a commercial door?
A deadlatch has a small auxiliary plunger riding alongside the main latchbolt. When the door closes, the plunger is held in by the strike and locks the latchbolt against being pushed back, so the latch cannot be shimmed or carded open. The 867F21 is that type of latchbolt, specified for commercial openings where a plain spring latch would be a security weakness.
4) Is the Corbin Russwin 867F21 a complete lock or just a replacement part?
Just the latch. The 867F21 is a latch component for a Corbin Russwin mortise lockset, sold to rebuild or repair an existing lock rather than to lock a bare door. You will still need the lock case, trim, cylinder and strike already in the opening. If you need a whole lock, look at the ML2000 Series mortise lockset instead.
5) Will a Codelocks replacement dual backset deadbolt work in place of the Corbin Russwin 867F21 deadlocking latch?
No - these are two different bolt types and are not interchangeable. The Corbin Russwin 867F21 is a deadlatch: a spring-actuated latchbolt with a deadlocking feature, operated by the lever or knob of a mortise lockset. The Codelocks replacement dual backset deadbolt is a deadbolt, a bolt thrown and withdrawn deliberately by key or code rather than by a latch retractor, so it does not hold a door closed on its own. If you are rebuilding a Corbin Russwin mortise lock that latches on close, you need the 867F21 deadlatch with its 2-3/4 inch backset and square corner front, not a deadbolt.
6) What finishes does the 867F21 deadlocking latch come in?
Four: 612 satin bronze, 613E dark oxidized satin bronze equivalent, 630 satin stainless steel, and BSP black suede powder coat. Match the front to the rest of the trim on the opening, 630 being the usual pick on institutional and healthcare doors where the existing lever and rose are satin stainless.
7) Does this latch need any wiring or power?
No. The 867F21 is a mechanical latch with no solenoid, switch or wire harness. If the opening is on an access control system and the lock is electrified, this is the wrong part for that lock case.
8) I need a replacement bolt for a code-entry lock, not a mortise lockset - what should I order instead of the 867F21?
The Corbin Russwin 867F21 is a mechanical deadlatch built as a genuine replacement component for compatible Corbin Russwin mortise lockset configurations, so it is the wrong part for a code-entry lock body. For that application the Codelocks replacement dual backset deadbolt is the deadbolt-function replacement part, supplied in a stainless steel finish. Match the part to the lock body you are servicing: mortise lockset rebuild takes the 867F21, a Codelocks unit takes the Codelocks bolt.
9) The Codelocks deadbolt is listed as dual backset - does the Corbin Russwin 867F21 cover more than one backset too?
No. The Codelocks replacement deadbolt is described as dual backset, meaning one bolt covers two backset dimensions. The Corbin Russwin 867F21 is a single fixed dimension: a 2-3/4 inch backset with a 1-1/8 inch square corner front. Measure from the door edge to the center of the lock spindle hole before ordering - if your mortise prep is not 2-3/4 inch, the 867F21 is not the correct latch for that door.
10) Is the 867F21 suitable for high traffic doors in a school or hospital?
Yes, it is a commercial-grade component intended for high-traffic institutional openings, offices, healthcare, education, retail and government buildings. For a facility standardizing repair stock, note the two variables you must match across your doors: the 2-3/4 inch backset and the square corner front.
