How Does it Work?

Multi-point locking offers increased security and stability to your door opening through creating more points of contact with your door jamb. 

A traditional deadlock or deadbolt locks in the middle of your door. In a multi-point locking system, the door locks in two or three separate places - typically the middle, top, and bottom - creating additional locking points and a tighter seal along the length of the door which can result in enhanced security. 


System Design

Multi-point locks can come in different designs, but usually include pairing a deadlock/deadbolt with a latch and/or additional bolts. 

This configuration can also include adding header or threshold bolts at the top and bottom of the jamb. 

Common Application: Exterior Single Door

A single door typically seen with a fixed pull or a longer offset pull that runs the length of the door. You may choose multi-point locking to avoid unauthorized entry. 

The top and bottom bolts help with preventing jamb spread. 

Common Application: Exterior Double Doors

Multi-point locking is the most simple and secure way to properly secure double doors because you have to pin both leaves to the frame. A single lockbody alone would allow a door to be vulnerable. Adding both a threshold and header bolt can prevent prying.

Paired with the proper trim can also provide ADA compliance. 

Common Application: Exterior Sliding Doors

When faced with a sliding door or window (i.e., think quick service windows), using a hookbolt instead of straight bolt is the way to go. The hook shape of the bolt is designed to prevent jamb spread, adding an extra layer of security. Add a header and threshold bolt to complete the solution.
