Deltana BTP500 Spacer-Tail Piece

No. The Deltana BTP500 is a steel spacer and tail piece, the part that spans the gap behind a cylinder and carries the turning motion into the lock mechanism. The GMS KIT-PART04 is a collars kit, a cylinder part that sits on the face of the door as a trim ring around the cylinder. If the cylinder turns but does not drive the lock, the tail piece is the part in question; if the cylinder sits proud or the escutcheon gap shows, the collar is.

Not usually. The Deltana BTP500 is a spacer and tail piece that works behind the cylinder, not at the strike. For a latching or holding problem at the jamb, look at strike-side hardware such as the ABH 1890 Series roller latch with full lip cast strike and 5/16 inch adjustable projection, the ABH 1895 Series roller latch with T strike and 1/2 inch adjustable projection, or the Cal-Royal ASA478 template ASA strike.

No. The BTP500 is offered as a single configuration, one model with no length, finish, or handing choices to specify. You order it as-is, per piece.

They solve different problems. The Deltana BTP500 spacer-tail piece adds spacing behind the cylinder and extends the drive into the lock. The GMS ICM7-ST is a Best SFIC straight mortise housing with a Yale cam, 7-pin, which is a threaded body that accepts a small format interchangeable core and is selected by its own length. Choose the mortise housing when you are building an SFIC mortise cylinder; choose the BTP500 when an existing cylinder needs a spacer and tail piece behind it.

No. The GMS IC6-26D is a 6-pin small format IC core and the IC7-26D is the 7-pin version, both supplied un-combinated without keys, pins, springs or caps. Those are the keyed element that drops into a housing. The Deltana BTP500 is a steel spacer and tail piece, a non-keyed mechanical part behind the cylinder. A core will not bridge a spacing gap and a tail piece will not accept a key.

Deltana classes the BTP500 spacer-tail piece as commercial door hardware, so it's intended for commercial openings rather than residential-only duty. That's the use classification Deltana assigns; it isn't a grade or a fire rating.

Depends on which part failed. For cylinder work, GMS sells a collars kit and small format IC cores in 6-pin and 7-pin, un-combinated, plus a Best SFIC straight mortise housing in 7-pin with a Yale cam. If the problem is at the frame instead of the door, Cal-Royal's ASA478 is a template ASA strike, and Trimco's 1268 anchor plate runs 3-1/2 inches in diameter. For a privacy latch that won't release, Cal-Royal's PDL-200 is the steel disengage tool.

Only as a mechanical part behind a cylinder. It is a steel spacer and tail piece for commercial door hardware with no electronic function. Programming and credential work on electronic locks is handled by separate accessories such as the Alarm Lock DTMIII data transfer module with 200-lock capacity, the PCI2-U USB computer interface cable with DL-Windows software, or the PRE2 proximity card enroller for HID and iClass.
