Adams Rite 91-0912 121 – Frequently Asked Questions

1) What does the Adams Rite 91-0912 adapter plate actually do?
It's a cover plate used when you convert a 4590 or 4560 series lock over to a latch lock setup. That conversion leaves an open hole where the indicator used to sit, and the 91-0912 covers it so the door face looks finished and the lock operates properly after the changeover. It is a genuine Adams Rite replacement part, not the lock itself.
2) Does the 91-0912 cover the indicator hole on the left or the right side?
Left. The 91-0912 is the version that covers the hole left by the indicator on the left-hand side of the conversion. If the opening you are working on leaves the indicator hole on the opposite side, this is the wrong plate for that door.
3) Will the 91-0912 plate work on a lock other than a 4590 or 4560?
No. The plate is cut for the 4590 and 4560 series lock families during a latch lock conversion. On any other Adams Rite series, or on a lock that was never indicator-equipped, the hole pattern won't line up and you should source the cover specific to that lock.
4) Does buying the 91-0912 give me everything I need to convert a 4560 to a latch lock?
No. The 91-0912 is only the cover plate that hides the indicator hole after the conversion. The latch lock itself and any cylinder, cam or trim the changeover calls for have to be ordered separately. Order the plate alongside the conversion hardware so the door face is finished the same day you do the swap.
5) I manage a building with a mix of dark bronze and clear aluminum storefronts. Can I standardize on one 91-0912 plate?
Only if the doors share a finish. The plate is offered in 121 Dark Bronze Anodized and 130 Aluminum, so a mixed-finish property needs both to keep each entrance looking uniform. The part number and fit are the same either way; it's purely the visible finish that changes.
6) Is the 91-0912 a commercial part or is it okay for residential storefront doors?
It's catalogued and built as commercial door hardware, aimed at aluminum storefront entrances in offices, retail, schools, healthcare, industrial and municipal buildings. Nothing stops it going on a light-duty door, but the application it is made for is the commercial aluminum storefront opening.
