Solid Brass Mortise Cylinder

This 1-1/4 inch mortise cylinder is machined from solid brass bar stock to OEM specifications. It suits residential and light-commercial doors that require a standard-thread replacement cylinder with a polished brass finish. The unit ships keyed different so each lock operates independently.

Schlage C-K Keyway

The cylinder uses a Schlage C-K keyway with a five-pin tumbler, meaning only keys cut to that profile will operate the lock. Existing Schlage keys cannot be copied onto this cylinder unless they already match the C-K specification.

Indoor and Outdoor Durability

Solid brass construction resists corrosion on exterior doors while the polished US3 finish maintains appearance on interior hardware. No electronic components or moving assemblies exist to generate heat, noise or power draw.

Questions about this item

What does the 1-1/4" length mean when the cylinder is installed in a mortise lock?

The 1-1/4" length is the cylinder body size that fits standard door thicknesses; it threads into the lock housing with the 1.150 x 32 UNS thread.

How does the 1.150 x 32 UNS thread size limit which locks this cylinder can fit?

The 1.150 x 32 UNS thread only mates with mortise lock housings cut to that exact thread pitch and diameter.

What clearance does the 1.360" (34.5mm) cylinder face need in the door prep?

The 1.360" (34.5mm) face diameter requires a matching bore in the lock trim or escutcheon to sit flush.
