Deltana TPRC100 Tail Piece-Retaining Clip

It is the small steel clip that holds a cylinder tail piece in place so the tail piece cannot back out of the cylinder or lock body during operation. Deltana sells the TPRC100 as a single replacement part, priced and shipped each, so you can order just the clip when one is lost during a cylinder swap rather than replacing the whole cylinder.

Depends what failed. For cylinder rebuild bits, GMS sells a collars kit (KIT-PART04) and small format IC cores in 6-pin and 7-pin, un-combinated, with keys, pins, springs and caps not included. If the problem is at the strike rather than the cylinder, Cal-Royal's ASA478 is a template ASA strike, and Trimco's 1268 anchor plate comes in a 3-1/2 inch diameter. For a jammed privacy latch, Cal-Royal's PDL-200 is a steel disengage tool.

They are both small cylinder-area service parts, but they do different jobs. The Deltana TPRC100 is a steel tail piece retaining clip that holds the tail piece in place, sold by the each. The GMS KIT-PART04 is a collars kit, a cylinder part used to take up space and dress the cylinder face. If the tail piece is working loose, the TPRC100 is the part; if the cylinder sits too proud or too deep in the door, the collars kit is what addresses it. Many jobs end up needing both.

No. The GMS IC6-26D is a 6-pin small format interchangeable core and the IC7-26D is the 7-pin version, both supplied un-combinated without keys, pins, springs or caps - they are the keyed heart of the cylinder. The Deltana TPRC100 is a steel retaining clip for the tail piece, the flat bar that transmits turn from the cylinder to the lock. Swapping a core does not supply a retaining clip, and a clip does nothing about keying. Order the core for keying changes and the TPRC100 when the tail piece retention is the failure.

Both are worth checking. The Deltana TPRC100 is a steel tail piece retaining clip; if the clip has failed the tail piece can drift out of engagement so the cylinder spins without driving the lock. The GMS ICM7-ST is a Best SFIC straight mortise housing in 7-pin with a Yale cam, and it is the part to order when the housing or cam itself is the problem rather than the tail piece retention. Pull the cylinder and see whether the tail piece is loose or the cam is damaged before ordering.

Deltana classifies the TPRC100 as a commercial door hardware part. That matters for MRO and property management buyers standardizing repair parts across a building: it is catalogued alongside commercial door hardware rather than as a homeowner item.

Steel, both the material and the substrate. A steel spring clip is what you want in a retaining application on a cylinder tail piece, where a cast or plastic part would fatigue under repeated key turns in a multi-family or school entry.

No. Deltana offers the TPRC100 as a single model with no finish or size options. It is a concealed retaining clip, so finish is irrelevant once installed.

No. The Cal-Royal PDL-200 is a steel privacy door latch disengage tool for privacy, bed and bath functions - a tool you keep on the cart to open a locked privacy set. The Deltana TPRC100 is a steel component that stays in the door, retaining the tail piece behind the cylinder. A property manager stocking for turnovers would carry the PDL-200 as a tool and the TPRC100 as a replacement part.

They sit on opposite sides of the opening. The Trimco 1268 is a 3-1/2 inch diameter anchor plate and the Cal-Royal ASA478 is a template ASA strike for commercial doors - both are frame or door face components. The Deltana TPRC100 is a steel tail piece retaining clip that works inside the lock behind the cylinder. A commercial MRO stock list generally carries all three, because a clip does nothing for a worn strike and a strike does nothing for a tail piece that will not stay seated.
