Solid Brass Mortise Cylinder

This MAXTECH cylinder is a solid brass replacement unit with a polished US3 finish. It uses a Yale YA1 keyway and a standard five-pin tumbler mechanism. The cylinder is supplied keyed different for individual security.

Verify Thread And Face Dimensions

Confirm that your existing mortise lock accepts a thread size of 1.150 x 32 UNS before ordering. Measure the cylinder face to ensure it matches the 1.360 diameter (34.5mm). Check that a 1-1/8 inch cylinder length suits your door thickness.

Suits Standard Mortise Retrofits

This cylinder fits most mortise locks using the standard cam #1 and the specified thread pattern. It is not suitable for locks requiring a different cam profile, a longer or shorter cylinder body, or an alternative keyway. Buyers needing master-keyed or keyed-alike sets should look elsewhere.

Questions about this item

Does the cylinder come with a cam and keys, or do I need to buy them separately?

The cylinder includes a Standard Cam #1 and two keys cut to the Yale YA1 keyway; no extra parts are required for a standard mortise lock installation.

How do I decide between the 1-1/8" length and the other available sizes?

Measure the existing cylinder from the centre of the mounting screw to the outer face; choose the 1-1/8" model when that measurement matches 1-1/8 inch.

What does the 1.150 x 32 UNS thread size mean when I fit this cylinder in my door?

It means the cylinder screws directly into any mortise lock body cut to the 1.150-inch diameter with 32 threads per inch, the common UNS standard for US mortise hardware.
