Solid brass mortise cylinder

This solid brass mortise cylinder measures 1-1/4 inches in length and fits standard mortise locks with a 1.150 x 32 UNS thread. The cylinder face diameter is 1.360 inches (34.5mm) and it operates with a Segal SE1 keyway. It is supplied keyed different and features a Standard Cam #1 for broad compatibility.

Polished brass finish durability

The US3 polished brass finish resists corrosion for indoor and outdoor installations. Solid brass construction provides reliable mechanical operation without electronic components. No power draw or noise is generated during normal use. The five-pin tumbler mechanism engages smoothly with each key turn.

Sustained mechanical operation

Under repeated locking cycles the solid brass body maintains dimensional stability and thread integrity. The standard cam continues to actuate the lock mechanism without binding. Keyed-different cylinders ensure each unit has a unique combination for security. The cylinder is designed for long-term service in residential and commercial doors.

Questions about this item

How do I install the 1-1/4" mortise cylinder with its 1.150 x 32 UNS thread?

Thread the cylinder into the mortise lock body by hand until the Standard Cam #1 aligns with the lock mechanism, then secure with the set screw; the step often missed is verifying cam engagement before tightening the screw.

What maintenance will the solid brass cylinder and 5 pin tumbler need over time?

Lubricate the keyway and tumbler pins annually with a dry graphite powder; avoid oil-based sprays that attract grit and cause the Segal SE1 key to bind.

Which dimension limits fitment on thick doors under sustained use?

The 1-1/4" cylinder length and 1.360 (34.5mm) face diameter determine maximum door thickness; if the door exceeds this length the cylinder cannot fully engage the lock body.
