Schlage A301-043 – Frequently Asked Questions
1) What does the Schlage A301-043 tailpiece fit?
The A301-043 cylinder tailpiece is made for Yale 5300 and 5400 Series LN levers. It is the piece that transmits cylinder rotation into the lever lockset, so it only belongs in those Yale LN lever applications, not in a Schlage lever chassis.
2) Is the A301-043 a whole cylinder or just the tailpiece?
Just the tailpiece. It is the flat drive bar that engages the cylinder to the lock mechanism, sold as a replacement part on its own. If the cylinder itself is worn or you are rekeying to a different keyway, you need a cylinder as well; the A301-043 only replaces the drive piece.
3) My Yale LN lever key turns but the latch does not retract. Will a new tailpiece fix it?
That symptom points at the cylinder-to-chassis link, which is exactly what this part is. A worn, bent, or wrong-length tailpiece lets the key turn without driving the lock. Replacing it with the A301-043 on a Yale 5300 or 5400 LN lever restores engagement without pulling and replacing the entire lockset.
4) Is this tailpiece rated for commercial door traffic or is it a residential part?
It is catalogued and built for commercial use, which is where Yale 5300/5400 LN levers normally live: offices, schools, healthcare, retail, warehouses, multi-tenant residential, and government buildings.
5) Is the A301-043 a genuine Schlage part?
Yes, it ships as an authentic Schlage component under model number A301-043. Despite the Schlage name, its application is the Yale 5300/5400 LN lever, so order by the model number rather than by the lever brand on the door.
6) How many tailpieces should I order for a building standardizing on Yale LN levers?
One A301-043 covers one lever. Property managers and MRO buyers keeping a fleet of Yale 5300/5400 LN openings running usually stock several, since the tailpiece is the small wear item that takes a whole door out of service while the lever body itself is still good.
