Magician Paul Svengari uses some of his magic in this film to demonstrate the proper steps for securing business aluminum and glass doors.
Abstract
Aluminum is a soft metal which is susceptible to the jampeeling type of forced entry; aluminum and glass doors can be opened with a dead bolt still locked. For greater security the doors should be steel reinforced with a strike plate and, because they are also narrow, should have a swinging or pivoting bolt with a hardened insert and a tapered cylinder guard. Glass doors should have glazing materials that are tempered or laminated. For wood, steel, or aluminum and glass double doors, a barrier steel bar or a two-by-four is needed. Also, a three-point locking system, a solid core door, and a combination of two locks--a dead locking latch and a tubular, 2-inch dead bolt with cylinder guard and hardened insert--are recommended. Twelve inches of fill should encase the door frame, as well as nonremovable hinge pins and a strike secured with long screws.
