Mul-T-Lock hardware for your door
Mul-T-Lock high-security cylinders are used on residential and commercial doors. MT5+, Interactive+ and Hercular hardware come in different formats; the existing door preparation and cylinder type determine which replacement fits. Discuss key-control requirements when choosing the cylinder.
- MT5+ patented cylinders — rim, mortise, deadbolt, padlock formats
- Interactive+ cylinders for doors that need restricted key copies
- Hercular Grade 1 deadbolt with reinforced strike
- Junior padlocks and Traveller portable padlocks
- Cylinders keyed alike across residential and commercial doors
Choose what fits. Not just a brand.
The door and its frame
A cylinder cannot fix a sagging door. Check hinges, strike alignment and frame damage before choosing replacement hardware.
The existing preparation
Backset, door thickness, cylinder format and handle spacing determine what fits. The brand alone does not establish compatibility.
How the opening is used
A house deadbolt, storefront latch and commercial exit device do different jobs. Hardware must match the opening and its use.
