Schlage 09-992 – Frequently Asked Questions
1) What exactly comes in the Schlage 09-992 mortise cylinder service kit?
Four pieces total: one 1-1/8 inch B520-721 back housing, two B520-693 housing screws, and one B520-691 cam screw. It is a parts kit only, so no plug, pins, keys, cam or cylinder body are included. If you need the cam itself or a keyed plug, those are ordered separately.
2) I stripped the cam screw on a Schlage modular mortise cylinder. Is this the right part to order?
The B520-691 cam screw in the 09-992 kit is the correct fastener for cam attachment on Schlage modular mortise cylinders. The kit also carries two B520-693 housing screws and a 1-1/8 inch back housing, so you get the other small parts that commonly get chewed up during the same service.
3) Does the 09-992 kit change the keying on my cylinder?
No. The 09-992 supplies only the back housing and the housing and cam screws, so nothing in it touches the keyway, pinning or key control. Your existing plug and pin stack carry over, and the cylinder stays on the same key after the housing is replaced.
4) Is the Schlage 09-992 a commercial part or residential?
Commercial. Schlage classes the 09-992 as a commercial installation accessory within its parts line, which is why it turns up in office buildings, schools, hospitals, government facilities and multi-tenant residential where modular mortise cylinders are standardized across a lot of doors.
5) Do I need to remove the mortise lock from the door to use this kit?
The 09-992 rebuilds the cylinder itself, not the lock body. The cylinder threads out of the mortise case, so the work is done on the cylinder once it is backed out. No modification to the lock or door prep is involved, since the parts are factory-dimensioned Schlage components for the modular mortise cylinder.
