1" Mortise Turn Knob Cylinder

This solid brass cylinder replaces the core in Adams Rite style mortise locks. It suits residential and light commercial doors where a thumb turn on the inside and no key on the outside are required. The Duranodic finish matches dark bronze hardware. It is sold keyed different for individual access control.

Installation fits standard mortise prep

The cylinder threads into a 1.150 x 32 UNS bore with a 1.360 inch face diameter. A 1 inch body length matches common door thicknesses. The Adams Rite Cam #2 engages the latch bolt directly. Mis‑threading or forcing the cylinder into a non‑standard cam pocket are the usual issues; verify the cam cutout before tightening.

5 pin tumbler with thumb turn only

The five pin chamber provides basic pick resistance for interior offices, store rooms or secondary entries. It does not accept a key on the exterior, so it cannot secure a primary entrance that requires keyed access from both sides. For doors needing double cylinder function, a different cylinder type is required.

Questions about this item

How do I confirm the 1.360 inch cylinder face seats flush after installing the 1" mortise turn knob cylinder?

Thread the cylinder into the mortise body until the 1.360 inch face sits flat against the door surface, then operate the thumb turn through a full rotation — the Adams Rite cam should engage the latch smoothly without binding.

What components come in the box and what must I supply separately?

The box contains the solid brass cylinder with the Adams Rite #2 cam installed and the 1.150 x 32 UNS threads; you must provide the mortise lock body, mounting screws and any strike plate required for your door.

Which cylinder length should I select for my door thickness?

Choose the 1" length when your door thickness matches that cylinder size; other lengths are offered for thicker or thinner doors, so measure the existing cylinder or door before ordering.
