Solid brass mortise cylinder

This 15/16" mortise cylinder is machined from solid brass bar stock to OEM specifications. The Polished Brass US3 finish suits both indoor and outdoor doors. It accepts a Segal SE1 keyway and ships keyed different for individual access control.

Threaded fit with Adams Rite cam #2

The cylinder uses a 1.150 x 32 UNS thread and a 1.360 (34.5mm) face diameter for direct replacement in compatible mortise locks. Solid brass construction resists corrosion without relying on coatings that wear away. A five-pin tumbler provides standard mechanical security.

Keyed different with Segal SE1 keyway

Each unit arrives cut to a unique key code so multiple cylinders do not share a single key. The Segal SE1 keyway limits key duplication to blanks matching that profile. No additional cams, screws or programming tools are included in the box.

Questions about this item

How do I install the 15/16" mortise cylinder with the 1.150 x 32 UNS thread, and what step is often missed?

Thread the solid brass cylinder into the mortise lock until the 1.360 diameter face seats flush, then secure the set screw through the lock body to lock the Adams Rite Cam #2 in place; the step often missed is tightening that set screw after the cylinder is fully seated.

What maintenance or replacement will the Segal SE1 keyway and 5-pin tumbler need over time?

Lubricate the 5-pin tumbler annually with dry graphite powder to keep the Segal SE1 keyway operating smoothly; replace the cylinder only if the key binds after cleaning or if the brass cam shows visible wear.

What is the first limit that appears when the lock sees heavy daily use?

The Adams Rite Cam #2 interface will show wear before the solid brass body, eventually causing the cam to slip against the lock mechanism and preventing the bolt from throwing cleanly.
