Schlage B520-541 – Frequently Asked Questions

1) Which Schlage lock series does the B520-541 security insert fit?
The B520-541 security insert works with S200 Series locks built after February 26, 2008, and with B100, B250, B400, B500, E, B, H, and MD Series collar assemblies. If you are servicing an S200 that predates that February 2008 cutoff, this is not the insert for it.
2) Is the B520-541 a complete lock or just a replacement piece?
It is a replacement part only, a security insert that seats inside a compatible Schlage collar assembly. You are not getting a cylinder, deadbolt or collar with it, so the existing lock body and collar have to be serviceable for this to solve the problem.
3) I manage a building with several different Schlage deadbolt series on the doors. Can I stock one insert for all of them?
For the most part, yes. The B520-541 covers B100, B250, B400 and B500 Series collars plus E, B, H and MD Series, and S200 Series locks made after February 26, 2008. That lets a maintenance shop carry one insert instead of a separate part for each family, as long as no older pre-2008 S200 hardware is in the mix.
4) Is this a genuine Schlage part or an aftermarket copy?
Genuine Schlage. The B520-541 is made to Schlage's own specifications for the collar assemblies it serves, which is what keeps the insert seating correctly rather than binding in the collar.
5) How do I order the Schlage security insert, and are there finish or size choices?
There is one item to order, part B520-541. No finish, size or handing choice applies, so the only thing to confirm before ordering is that the lock it is going into is one of the covered series.
6) Is the Schlage B520-541 insert rated for commercial use or is it a residential part?
Commercial. It is catalogued as a commercial-grade replacement insert, and the series it serves (B500, S200, MD) are Schlage's commercial mechanical lock platforms. Typical use is office buildings, schools, healthcare, retail, industrial facilities, multi-tenant residential and government buildings.
