Schlage A501-991 – Frequently Asked Questions

1) I'm restocking parts for a building full of Schlage A-series knob locks. Is this the right tailpiece to keep on the shelf?
If those knobs run conventional cylinders in the A85 or H185 configuration, yes, the A501-991 is the tailpiece to stock. Check the knob style first though: Orbit knobs are excluded from this part, so a mixed fleet with Orbit trim will need a second part number alongside it.
2) What does a cylinder tailpiece actually do on a Schlage A85 knob lock?
The tailpiece is the flat bar that transfers the turn of the key cylinder into the lock mechanism inside the knob. When it wears, bends, or shears, the key turns but the lock does not operate. The A501-991 is the OEM tailpiece that restores that cylinder to knob engagement on A85 and H185 conventional cylinder assemblies.
3) Do I need to modify the knob or cylinder to install the A501-991?
No modification. The tailpiece drops into compatible A85 and H185 knob conventional cylinder assemblies as a direct replacement, so a locksmith pulls the cylinder, swaps the tailpiece, and reassembles.
4) Is the A501-991 a genuine Schlage part or an aftermarket copy?
It's a genuine Schlage OEM replacement part built to original equipment specification, not an aftermarket equivalent. For facilities that standardize on Schlage and need the repaired lock to behave exactly like the original, that matters more on a small internal part than almost anywhere else.
5) Is this tailpiece rated for commercial door traffic or is it a residential part?
Commercial. The A501-991 is classified as a commercial part within Schlage's mechanical lock line, and it's the tailpiece used in A85 and H185 assemblies found in offices, schools, healthcare buildings, retail, warehouses, multi-tenant residential and government facilities.
