Choose Lockwood Deadlock Installation for the Ultimate Security

Standard lock and key mechanisms operate with a spring to hold the bolt in place. A deadlock or deadlatch lock is a locking mechanism which allows opening only through rotation of a lock cylinder. Deadlocks make entry into a building incredibly difficult without the right key. Lockwood is one of the industry’s leading names in deadlocks, and the Lockwood 355 deadlock is one of the most popular models known for its strength, durability, and reliability. To find out more or to arrange installation of a Lockwood deadlatch, get in touch with us today.

Deadbolt for Door – Single or Double Cylinder?

There are different types of deadbolts; the most common one is the single-cylinder deadbolt which has a twist knob on the inside to open and close, and a key on the outside. Double-cylinder deadbolts are slightly less common, but offer more security, as they require a special key to open/close the deadbolt from both inside and outside the door. For residential security, a single-cylinder deadbolt is the ideal solution.
