1" Mortise Turn Knob Cylinder

The Kaba Group 7161TK2-26D is a solid brass mortise cylinder with a satin chrome US26D finish. It measures one inch in length and features a 1.360 inch diameter face with a 1.150 x 32 UNS thread size. The unit operates via an interior thumb turn and has no exterior keyway, making it suitable for indoor or outdoor doors requiring single-sided operation.

Replaces worn or mismatched cylinders

This cylinder fits mortise locks accepting an Adams Rite Cam #2 and the specified thread dimensions. The jump is worth it when an existing cylinder binds, fails to engage the latch, or presents a finish that no longer matches the hardware set. Its five-pin tumbler mechanism restores smooth actuation without altering the door prep.

Fits standard mortise lock bodies

Installation requires a mortise pocket cut for a 1.360 inch diameter cylinder face and 1.150 x 32 UNS threading. The solid brass construction resists corrosion in exterior applications. The thumb-turn-only design frees the exterior side from key management but cannot secure an entry point that requires keyed access from both sides.

Questions about this item

Will the 1.150 x 32 UNS thread fit my existing mortise lock body?

Yes, the cylinder uses a 1.150 x 32 UNS thread that matches standard mortise lock bodies with that thread specification.

How do I install the Adams Rite Cam #2 correctly, and what step is often missed?

Thread the cylinder into the lock body until the cam aligns with the latch mechanism, then secure the set screw; the missed step is verifying cam rotation engages the bolt before tightening.

When should I replace the solid brass cylinder or its 5-pin tumbler mechanism?

Replace the cylinder if the thumb turn binds, the cam slips, or the 5-pin tumbler no longer turns smoothly after lubrication.
