Satin Chrome Mortise Turn Knob Cylinder

The Ilco 41651SC1-26D is a solid brass mortise cylinder with a captive thumb-turn and no keyway, intended for doors that need inside-only locking. It suits residential and light-commercial openings where a 15/16 inch cylinder length matches the door thickness.

Capacity and headroom

The cylinder face measures 1.360 inches (34.5 mm) in diameter and uses a standard #1 cam compatible with Adams Rite and similar mortise locks. A five-pin tumbler mechanism provides conventional security; the design does not accept a key, so it cannot be operated from the outside.

Build quality and connectors

Machined from solid brass bar stock to OEM specifications, the cylinder carries a satin chrome US26D finish that resists wear in indoor and outdoor environments. Threads are 1.150 x 32 UNS, allowing direct installation into standard mortise lock bodies without adapters.

Questions about this item

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

Yes, the cylinder uses a 1.150 x 32 UNS thread and a 1.360 (34.5 mm) face diameter, the standard dimensions for most mortise locks on the market.

How can I confirm the cylinder operates correctly after installation?

Turn the captive thumb turn; the standard cam #1 should engage the lock bolt cleanly and the solid brass construction should feel firm with no wobble.

Does the 41651SC1-26D come with a key or mounting screws?

The cylinder has a thumb turn with no key and ships as the cylinder only; keys, mounting screws and any additional cams must be purchased separately.
