Schlage B520-723 – Frequently Asked Questions

1) What is the Schlage B520-723 back housing used for?
The B520-723 is the mortise cylinder back housing, the 1-3/8 inch body component that the mortise cylinder assembles into. It is a service part, not a complete cylinder, so you still need the cylinder plug, keying, cam and mounting hardware to build a working cylinder.
2) Is the Schlage B520-723 a complete mortise cylinder I can drop into a lock?
No. The B520-723 is only the back housing for a mortise cylinder in the 1-3/8 inch length. If you need a keyed, ready-to-install unit, order a complete Schlage mortise cylinder instead of this housing.
3) Will the Schlage B520-723 work with a 1-1/8 inch mortise cylinder?
No. The B520-723 housing is the 1-3/8 inch length. Mortise cylinder lengths are not interchangeable, so a 1-1/8 inch or 1-1/4 inch cylinder needs the housing built for that length. Measure the existing cylinder from the face of the collar to the back before ordering.
4) I manage a building with Schlage mortise locks. Can I use the B520-723 to rebuild cylinders in house?
Yes, if your locksmith or maintenance tech is rebuilding mortise cylinders that use the 1-3/8 inch length. The B520-723 gives you the back housing as a replacement part, which is useful when a housing is damaged or drilled and the plug and keying are still good. It does not change keying on its own.
