Solid brass dummy cylinder for mortise locks

The Ilco 7160DC-03 is a solid brass dummy mortise cylinder with a polished brass US3 finish. It measures 1 inch in length and features a thumb turn with no keyway. This replacement part suits residential and commercial doors that need a fixed interior turn without an exterior key.

Thread and cam dimensions limit interchangeability

Installation requires a mortise lock body with a 1.150 x 32 UNS thread and a cylinder face diameter of 1.360 inches (34.5 mm). The Adams Rite cam #2 must match the lock mechanism. Cylinders with different threads, face diameters or cam styles will not fit.

Thumb-turn-only operation defines the use case

The cylinder provides a thumb turn on one side and no key access on the other. Buyers who need keyed entry from both sides or a double-cylinder function cannot use this model.

Questions about this item

Which cylinder length should I choose for a standard 1" mortise pocket?

The 1" length matches a standard mortise pocket; the cylinder face is 1.360 (34.5mm) diameter and the thread is 1.150 x 32 UNS, so it fits typical Adams Rite Cam #2 installations.

What does the 1.360 (34.5mm) cylinder-face diameter mean once the lock is installed?

That diameter is the visible face that sits flush with the door edge; it covers the mortise cut-out and aligns with the Adams Rite Cam #2 for proper thumb-turn operation.

Will the 1.150 x 32 UNS thread work with my existing mortise body?

Yes, the 1.150 x 32 UNS thread is the industry standard for dummy mortise cylinders and mates directly with compatible mortise lock bodies using the Adams Rite Cam #2.
