Introducing the Lockmaster Lockcase with a hook and single spindle unsprung mechanism, designed for reliable operation and security.
Operation: Single spindle version
Important Notes:
Ensure the latch is not pushed in before fitting the case to the strip, as this may cause it to stick.
If your lock features a hold-back spindle, you can release the latch by turning the spindle.
For locks with a hollow white plastic piece in the hold-back spindle hole, insert a screwdriver into the face of the lock and push down on the white plastic piece to release the latch.
Once installed, the handle will operate the latch through its normal cycle without issues.
Additional Information:
This product is also known as the Ultimate Collection. The Yale Lockmaster Key Turn gearboxes have a distinct appearance compared to regular Lockmaster gearboxes, featuring a corner of the lock removed.
Key Turn Gearbox: Available in a 45mm backset only.
Gearboxes are secured to faceplates with three screws and are not interchangeable with other Lockmaster locks.
When measuring the backset, remember to allow 2-3mm for the faceplate. For example, a 28mm backset gearbox will measure 25mm when not attached to the strip.
We offer a variety of associated products for Lockmaster Key Turn gearboxes, including multipoint door locks, keeps, spindles, handles, and accessories.
