Solid Brass Mortise Cylinder

This solid brass mortise cylinder fits doors that need a 1-1/4 inch replacement unit. The polished brass finish matches existing hardware on interior and exterior doors. It is keyed different with an Arrow AR1 keyway for individual access control. Installers and property owners use it to refresh worn cylinders without changing the whole lock body.

Upgrade From Worn Original Cylinders

The cylinder replaces an existing mortise cylinder that has become sticky, loose or hard to turn. A jump is worth it when the old cylinder face diameter measures 1.360 inches and the thread matches 1.150 x 32 UNS. The standard cam #1 works with most common mortise lock bodies on the market. Different lengths are offered for other door thicknesses.

Check Thread And Face Diameter First

Verify that the current cylinder uses a 1.150 x 32 UNS thread and a 1.360 inch face diameter before ordering. Confirm the door thickness suits a 1-1/4 inch cylinder length. Ensure the lock body accepts a standard cam #1 configuration. The Arrow AR1 keyway requires matching key blanks for cutting new keys.

Questions about this item

What thread size and cylinder face diameter does the 1-1/4" mortise cylinder need to fit my lock?

The cylinder uses a 1.150 x 32 UNS thread and has a 1.360 inch (34.5mm) face diameter.

Which cam comes installed and how do I avoid misaligning it during installation?

It ships with Standard Cam #1; the common mistake is not rotating the cam to the correct position before threading the cylinder into the mortise body.

When will I need to replace the cylinder or rekey it?

Replace if the brass shows heavy wear or the 5 pin tumbler mechanism binds; rekey when you want a different Arrow AR1 key code.
