5050 Mortise Lock

The 5050 mortise has a 50 mm setback, meaning the lock hole sits 50 mm back from the front edge of your door. With a compact 50 mm body depth, it’s a balanced fit for most standard doors. This mortise also includes a built-in deadbolt for added security, making it both simple and reliable.

3585 Mortise Lock

The 3585 mortise comes with a 35 mm setback, placing the lock hole closer to the edge of the door. Its longer 85 mm body depth provides more room inside for the locking parts. Like the 5050, it also has a deadbolt, giving slimmer or narrower doors strong, secure protection.

⚠︎ Please make sure you’ve selected the correct mortise size for your door before checkout.
