1" Solid Brass Mortise Cylinder

This 1" mortise cylinder is machined from solid brass bar stock and finished in US3 polished brass. It uses a Yale YA1 keyway with a five-pin tumbler and ships keyed different. The cylinder suits residential or commercial doors that accept a standard mortise thread.

Adams Rite Cam #2 and thread fit

The cylinder comes with an Adams Rite Cam #2 already fitted and a thread size of 1.150 x 32 UNS. Installation requires unscrewing the old cylinder and threading this unit into the mortise body; the cam engages the lock mechanism directly. Mis-threading or forcing the cylinder can damage the 32-thread pitch, so turn by hand until fully seated.

Verify thread, face diameter and cam before ordering

Confirm the existing mortise housing uses a 1.150 x 32 UNS thread and a cylinder face diameter of 1.360 (34.5 mm). Check that the lock body accepts an Adams Rite Cam #2 or that the cam can be swapped for the profile your hardware requires. Doors needing a different cylinder length or keyway will not work with this model.

Questions about this item

How do I confirm the mortise cylinder is operating correctly after installation?

Turn the Yale YA1 key in the 5-pin tumbler; the Adams Rite Cam #2 should rotate smoothly to retract the latch without binding.

What components are included and what must be purchased separately?

The box contains the solid brass 1" mortise cylinder with US3 polished brass finish, Adams Rite Cam #2 fitted, and two cut keys for the Yale YA1 keyway; mounting screws and any alternate cams are not supplied.

Which cylinder length should I select for my door thickness?

Choose the 1" length when your door preparation matches the 1.150 x 32 UNS thread and 1.360 (34.5 mm) face diameter; other lengths are offered for thicker or thinner doors.
