Solid Brass Mortise Turn Knob Cylinder

The Maxtech B1TK2-03 is a new solid brass mortise turn knob cylinder with a polished brass US3 finish. It measures one inch in length and uses a thumb-turn keyway that requires no key for operation. The cylinder is supplied keyed different in a single box.

Thread Size and Cylinder Face Limits

The cylinder fits mortise locks with a thread size of 1.150 x 32 UNS and a cylinder face diameter of 1.360 (34.5mm). Installations with different thread pitches or face diameters will not accept this cylinder without modification.

Replaces Worn Brass Cylinders

This unit replaces an existing mortise cylinder of the same one-inch length, thread specification and face diameter. The upgrade is worthwhile when the original cylinder is corroded, damaged or when a thumb-turn function is preferred over a keyed exterior.

Questions about this item

Should I choose the 1" size or a different length for my door?

The 1" length matches doors built for that cylinder depth; select a longer or shorter version only if your door thickness requires a different size.

What does the 1.150 x 32 UNS thread mean when I install the cylinder?

It is the exact thread pitch and diameter that screws into a mortise lock body with the same 1.150 x 32 UNS specification.

Will the Adams Rite Cam #2 work with my existing mortise lock?

The cylinder ships with an Adams Rite Cam #2; it fits locks designed for that cam, and other compatible cams can be substituted if needed.
