Triad Square Slimline Deadbolt - Single Cylinder Key/Turn

The Triad Square Slimline Deadbolt (Single Cylinder Key/Turn) by Zanda adds a robust layer of security to your home. You commonly see deadbolt locks on exterior doors, including front entries, back doors, and garage access points, because they resist forced entry better than standard latches.

How a Deadbolt Functions

A single cylinder deadbolt operates with a key on the outside and a thumb-turn on the inside. You lock or unlock the door by turning the thumb-turn or inserting the key, providing reliable daily protection for residential homes and commercial buildings alike.
