There are many ways to accomplish forcible entry objectives when faced with challenging obstacles, such as the rear door of a commercial occupancy that is typically secured by a horizontal security crossbar, indicated by exposed rounded carriage bolt heads seen on the exterior (photo 1). These carriage bolts extend through the door, securing multiple brackets inside that support the security crossbar horizontally on the interior (photo 2).
Traditional ways to gain entry through these challenging doors include shearing off the carriage bolt heads with a power saw, the blade of an ax, or the adz end of a halligan and cutting through the multiple locking mechanisms that secure the door. Depending on the wall’s construction, consider breaching the wall at the rear of the occupancy if efforts to force the door fail. However, this alternate entry method may also fail because of obstacles inside such as packed shelving and heavy machinery.
