Schlage A501-878-1 – Frequently Asked Questions

1) What does the Schlage A501-878 faceplate adapter actually do?
It adapts a 1 inch latch faceplate to a 1-1/8 inch faceplate opening, so a latch prepped for the narrower plate drops into a door mortise cut for the wider one. It's a plate only, not a latch and not a lock, so you keep the existing latch and use the adapter to close out the prep.
2) Will the A501-878 adapter work with my Schlage A Series knob lock?
A Series is exactly what it's built for. The A501-878 is listed as an A Series part, so it suits Schlage A Series cylindrical knob locksets. It is not a fit for other Schlage lines such as ND or L Series mortise, which use different latch and faceplate parts.
3) I have a 1-1/8 inch faceplate cut in the door edge but a 1 inch latch face. What part fixes that?
That's the exact gap this adapter covers. The A501-878 takes a 1 inch faceplate up to 1-1/8 inches, which lets you reuse the existing 1-1/8 inch door edge prep instead of re-mortising or filling and re-cutting the edge. Useful on retrofit work where the door was prepped for older or different hardware.
4) Do I need to order the A501-878 faceplate adapter in a specific finish?
Yes, order it to match. Schlage parts of this kind are finish specific, so the adapter is bought in the finish that matches the latch face and lockset already on the door. Ordering the wrong finish means a visible mismatch on the door edge, which matters most when you're standardizing a run of openings across a building.
5) Is the Schlage A501-878 adapter rated for commercial door use?
Commercial. It's a genuine Schlage commercial replacement part for the A Series line, so it's appropriate for apartment, office, school and other institutional openings running A Series cylindrical hardware rather than residential-grade product.
