Schlage A301-337 – Frequently Asked Questions

1) What door thickness does the Schlage A301-337 tailpiece cover?
The A301-337 tailpiece is sized for doors 2 inches to 2-1/2 inches thick. If your door falls outside that band, this is the wrong tailpiece length and the cylinder will not engage the knob chassis correctly. Measure the leaf at the lock prep before you order, since a thicker or thinner door takes a different tailpiece from the A301 group.
2) Which Schlage locksets does the A301-337 tailpiece work with?
It fits Schlage A Series, H Series, and D Series knobs in non-hotel functions, used with a modular cylinder. Orbit style knobs are the exception and are not covered. If the lock on the door is a lever rather than a knob, or a hotel function, this is not the part.
3) My Schlage knob key turns but the latch does not retract. Is the tailpiece the problem?
That symptom usually points at the tailpiece, which is the flat blade that carries rotation from the cylinder to the knob chassis. A bent, worn, or wrong-length blade lets the key turn without driving the retractor. On A, H, or D Series non-hotel knobs with a modular cylinder on a 2 to 2-1/2 inch door, the A301-337 is the replacement blade.
4) Does the A301-337 come with a cylinder or keys?
No. The A301-337 is the tailpiece alone, a replacement blade meant to pair with a Schlage modular cylinder you already have or order separately. Ordering it will not get you a keyed cylinder, a knob, or a chassis.
5) Is the A301-337 an OEM Schlage part or an aftermarket copy?
It is a genuine Schlage component, model A301-337, made to OEM tolerances. For facilities standardized on Schlage A, H, or D Series knobs, that matters because an out-of-tolerance blade is the usual cause of a sticky or partial key turn after a repair.
6) Is this tailpiece suitable for high-traffic commercial doors or is it a residential part?
Commercial grade, intended for high-traffic institutional and commercial openings such as offices, schools, healthcare, retail, and multi-tenant buildings. It is a replacement part for servicing existing Schlage knob locksets rather than a component sold with new hardware.
