  • Advantages: Distributes the force of an effect across the whole frame, considerably minimizes warping, and develops a tight weather seal.

2. Flush Bolts

Flush bolts are usually set up on the leading and bottom edges of the inactive door panel.

  • Benefits: Keeps the inactive door securely in place, allowing the active door to lock versus it firmly. They stay concealed from view when the doors are closed.

  • How it works: It houses both the lock mechanism and the deadbolt within a single, durable metal box, providing remarkable strength compared to basic cylindrical bored locks.

4. Surface-Mounted Slide Bolts

  • Material Quality: Opt for solid brass, stainless-steel, or hardened steel elements that withstand deterioration, specifically for outside doors exposed to weather elements.
