DOOR JAMBS

Structurally, one of the most important parts of a door is the jamb (a.k.a frame). A door is only as strong as its weakest link, and all too often the weakest link is the jamb.

​This is especially true for security doors. You can install the best FE/BR (forced entry/bullet resistant) door in the world but if your jamb is not up to the job, you’ll still be able to kick the door in.

Door jambs are an easily over-looked piece of the puzzle. The jambs for the Shield Fortress series and Embassy series doors are constructed from 14 gauge galvanized steel with a unique L-shaped profile that protects the locking bolts from attack. Each locking bolt is protected in a steel pocket that ensures that if someone attacks the locking bolts, they can only do so one at a time.
