Tech Tip


Strike Hooks Add Stability and Security


Single doors are much easier to secure as compared to a pair of doors, which are more vulnerable to burglar attacks.  However, pairs of doors with a removable mullion make daily operations of moving large items in or out of a building much easier.  When using a mullion on a pair of doors with rim exit devices, leading to the exterior, Detex recommends the use of a mullion strike hookStrike Hook (Detex PN 100091).  Strike hooks add stability and security to the opening, and travel on the face of the door, directly behind the latch bolt, interlocking with the strike when the door is closed.  When the strike hook and strike are interlocked, prying the door away from the mullion becomes difficult.  Consider adding strike hooks to your application for added stability and security.
