Schlage L283-146 XL11-543 – Frequently Asked Questions

1) Will the Schlage L283-146 lock case work with my L9482 mortise lock?
That's exactly what it's built for. The L283-146 XL11-543 is the mortise lock case for the Schlage L9482 series, made to Schlage factory specification so it drops into the existing mortise pocket and restores the original function of the lockset. It is the core mechanical case, not a complete lockset, so your existing trim, cylinder and strike stay in place.
2) Do I have to order a left-hand or right-hand version of this Schlage mortise lock case?
No. The L283-146 case is field reversible, so one part covers both left-hand and right-hand openings. You set the handing during installation, with no extra parts and no separate handed SKU to specify on the order.
3) Is this a complete Schlage L9482 lockset or just the internal case?
Just the case. The L283-146 is the mechanical operating body that sits inside the door pocket of an L9482 mortise lock. Levers, roses, cylinder and strike are not part of it. If your trim is worn or the cylinder is being rekeyed, order those separately.
4) Is the Schlage L283-146 lock case suitable for high-traffic commercial doors?
Yes, it's a commercial part, not a residential one. Schlage builds the L-series case for office buildings, schools, healthcare facilities, government buildings and hospitality properties where the same opening cycles all day. Facility crews standardizing on L9482 hardware can stock this one case for every such door, since handing is set in the field.
5) My Schlage mortise lock has stopped retracting the latch. Do I replace the whole lock or just the case?
If the failure is mechanical (latch not retracting, lever feel gone, internal linkage worn) and the trim and cylinder are still good, the case is the part to change. The L283-146 XL11-543 is sold as an authentic Schlage replacement for the L9482, so swapping it restores original function without pulling the whole lockset or re-prepping the door.
6) What is the difference between the part number L283-146 and the XL11-543 marking on a Schlage lock case?
They identify the same component. Schlage lists this case as L283-146 XL11-543, a single model designation used for exact part matching when ordering an L9482 case. Quote the full string and you'll get the right case.
