Schlage Commercial L583-475 L Series Modular Cam for 1-1/4"; 1-1/2" and 1-3/4"

It is the modular cam that goes on the cylinder side of a Schlage L Series mortise lock, the part that transfers cylinder rotation into the lock case. It is a genuine Schlage service part for commercial mortise lock applications, not a complete cylinder or lock body, so you are ordering it to service or complete an existing L Series mortise installation.

Yes. The L583-475 modular cam covers the three standard mortise cylinder lengths used on L Series locks, 1-1/4, 1-1/2 and 1-3/4 inches, so one cam part number serves all three instead of a length-specific cam. Those are the usual mortise cylinder lengths you will find in commercial doors.

No. This cam is an L Series mortise part, and its stated compatibility is mortise locks only. Cylindrical locksets such as the ND or AL Series use a tailpiece arrangement, not a mortise cam, and rim cylinders on exit devices take a rim cylinder tailpiece. Ordering this for anything other than an L Series mortise lock will leave you with a part you cannot install.

It is a certified Schlage part for the L Series, so it is the same component the factory uses rather than an aftermarket substitute. For institutional and MRO buyers standardizing on L Series mortise hardware across a facility, that matters because the cam engagement in the lock case has to be exact for the cylinder to throw the latch reliably. Order under model L583475.

Many Schlage L Series service parts are finish specific, so when you are pulling parts for a mortise lock rebuild you have to match the finish of the visible trim. The cam itself sits inside the lock case, but any plate or trim part you order alongside it should be specified in the finish already on the door so the opening still matches the rest of the building.
