Schlage B520-653 – Frequently Asked Questions

1) Can I use the B520-653 tailpiece on a Schlage lock that isn't a B571?
No. The B520-653 is cut and formed specifically for the B571 lock series. Tailpiece length and blade shape have to match the lock body's drive, so putting it in another Schlage series risks incomplete engagement or a bolt that won't throw. Identify the lock model first and order the tailpiece Schlage lists for that series.
2) Will the Schlage B520-653 tailpiece work on a 2-inch thick door?
Yes. The B520-653 covers door thicknesses from 1-3/8 inches to 2-1/4 inches, so a 2 inch door falls inside its range, as does the standard 1-3/4 inch commercial door and the older 1-3/8 inch interior door.
3) Is this a genuine Schlage part or an aftermarket copy?
Genuine OEM. The B520-653 is made by Schlage to the original specification for the B571, which matters on a tailpiece because the fit tolerance between cylinder and lock body is what keeps the key turn smooth over thousands of cycles.
4) If my key turns but the deadbolt won't move on a Schlage B571, is the tailpiece the part to replace?
That symptom points at the tailpiece, yes. When the cylinder spins freely but the bolt stays put, the coupling between cylinder and lock body has worn, twisted, or is the wrong length for the door thickness. The B520-653 is the coupling part for the B571 and fits doors 1-3/8 to 2-1/4 inches thick, so match your door thickness to that range before you fit it.
5) Do I need to buy a new cylinder along with the B520-653 tailpiece?
Not if your existing cylinder is sound. The B520-653 is sold as the tailpiece alone, which is the point of it: you keep the keyed cylinder and the lock body and replace only the driven part. Order a cylinder separately only if the plug or keyway is also damaged.
6) Do I have to order a different B520 tailpiece for each door thickness in my building?
No. One part number, B520-653, covers the whole 1-3/8 to 2-1/4 inch range, so a property manager standardizing B571 locks across mixed-age doors can stock a single tailpiece rather than one per thickness. Anything thicker than 2-1/4 inches is outside what this part covers.
7) Is the B520-653 tailpiece rated for commercial door traffic?
It's classified as a commercial part, built for the duty found in office buildings, schools, healthcare, retail, warehouses, municipal buildings and multi-tenant residential, all of which Schlage names as typical applications for the B571 hardware it serves.
