Solid Brass Mortise Cylinder for Standard Doors

This 1-1/8 inch mortise cylinder is machined from solid brass with a US3 polished brass finish. It suits residential and commercial doors that accept a 1.150 x 32 UNS thread and a 1.360 inch cylinder face diameter. The Arrow AR1 keyway and five pin tumbler provide a conventional mechanical locking solution.

Straightforward Installation With Correct Cam

The cylinder uses a Standard Cam #1 and fits most mortise locks sharing the stated thread and face dimensions. Installation requires unscrewing the existing cylinder and threading this unit into the mortise body. Misalignment occurs when the cam does not engage the lock mechanism or when the cylinder face diameter differs from 34.5 mm.

Mechanical Limits of the Arrow AR1 Keyway

The Arrow AR1 keyway restricts key duplication to blanks cut for that specific profile. The five pin tumbler offers standard pick resistance but does not incorporate sidebar or high-security features. Buyers who need master-keyed systems, restricted keyways or cylinders longer than 1-1/8 inch should select a different product.

Questions about this item

How do I confirm the 1.150 x 32 UNS thread engages correctly after installation?

Turn the key in the Arrow AR1 keyway; the plug should rotate smoothly and the Standard Cam #1 must retract the latch without binding.

Which components are included in the box and what must I supply separately?

The box contains the solid brass mortise cylinder with Standard Cam #1 installed; you must provide the mortise lock body, mounting screws, and any other cam if your lock requires a different cam.

When should I choose the 1-1/8" length with 1.360 (34.5mm) face diameter over other sizes?

Select this version when your door thickness and mortise pocket match the 1-1/8" cylinder length and the 1.360 inch face diameter specified for the lock body.
