Schlage L283-112 – Frequently Asked Questions
1) Will the Schlage L283-112 lock case fit an older L9000 mortise lock?
Only if the lock was built after January 1998. The L283-112 case is specified for Schlage L9000 Series mortise locks manufactured after that date. On a pre-1998 L9000 body, the case is not the correct replacement, so check the age of the existing lock before you pull the door apart.
2) Do I have to order a left-hand or right-hand version of the L283-112 lock case?
No. Handing is set in the field on the L283-112, so one part covers left- and right-hand openings with no extra components to buy. That makes it a practical item to keep on the truck or in the shop for a building with doors swinging both ways.
3) What exactly does the L283-112 replace, the whole mortise lock or just the internal case?
Just the lock case, the mortise body itself. It is a factory-specified replacement for the case in an existing L9000 Series assembly, so your trim, lever, cylinder and strike stay in place and only the failed body is swapped. If what is worn is the lever or the cylinder, this is not the part.
4) Is this a genuine Schlage part or an aftermarket lock case?
Genuine Schlage. The L283-112 is an authentic Schlage component, which matters on an L9000 mortise body because the case has to index correctly with the original trim and cylinder prep in the door.
5) Is the L283-112 suitable for high traffic openings in schools and hospitals?
Yes. It is used in office buildings, schools, healthcare and government facilities, multi-tenant residential, retail and industrial buildings, which are exactly the settings L9000 mortise locks get specified for. For a facility standardizing on L9000, keeping L283-112 cases in stores lets maintenance restore a door without ordering a complete lock.
6) Does the lock function change when I install an L283-112 case?
The case is a like-for-like restoration of the existing L9000 assembly, not a function conversion. It brings the lock back to the way it worked, so if you need a different function such as storeroom instead of classroom, the case swap alone is not how you get there.
7) Can I use the L283-112 on residential interior doors?
It is a commercial part. The L283-112 is built to L9000 Series commercial standards and only belongs in an L9000 mortise lock, which is a commercial mortise product. Residential bored locksets take nothing from this family.
