How To Secure Your Doors

 

The majority of devices mentioned in this report cost very little. All of them will help reduce burglary and make your house or apartment more secure.

Begin with a home "security" check. Start with the front door and work clockwise around the entire inside of your home, finishing with the back yard, fence and shrubs, gates and garage.

Shrubbery should never block the view of your front door. This allows an intruder the opportunity of privacy to gain entrance. A wide angle viewer in the door lets you know your visitor in advance. This item is recommended over a chain lock. 

 

LOCKS, BOLTS AND HINGES 

A DEAD-LATCH: is an inexpensive lock set which keeps the burglar from simply slipping your door open with a plastic credit card. This method of entry is common in many areas, but very easy to prevent.

 

AUXILIARY DEADBOLT: 1" deadbolt, single cylinder with hardened cylinder guard, and thumb turn.

For extra security, a single cylinder dead bolt lock, with one inch throw and case-hardened insert, is recommended for all exterior doors. If you have easily breakable glass within 40 inches of a deadbolt lock, it should be augmented with a stronger type of glass or plastic to provide adequate security.

Most police departments do not recommend deadbolt locks for residential use. You may be adding additional security at the expense of personal safety with a double cylinder dead bolt. For example, you could lock yourself in and not be able to escape in case of fire or other emergency.

 

THE RIM LOCK: is a 1" dead bolt lock which is installed on the inside surface of the door. It is less expensive than other types of locks, but equally effective for security.

 

THE "JIMMY-PROOF" RIM LOCK: is another lock which is installed on the inside surface of the door. But this lock has vertical dead bolts, which is an approved locking device.

 

CANE BOLTS: 1/2" in diameter by 12" high installed at the top & bottom of the inactive door offers minimum security. Many homes with pairs of doors, use half-barrel slide bolts on the inactive door. These are weak and totally inadequate.

 

FLUSH BOLTS: Installed at the top and bottom of the inactive door or a pair of doors, flush bolts offer additional security, since the intruder cannot get at these devices to tamper with them if the doors are locked.

 

HINGE PROTECTION: Some exterior doors are improperly installed so that the hinges are installed from outside. To protect such a door from being lifted from its hinges by pulling the hinge pin, follow these simple steps: (1) Remove two screws, opposite each other, from both leaves of the hinge. (2) Insert screw or concrete nail into jamb leaf, protruding 1/2". (3) Drill out the opposing screw hole in the door. Do this in the top and bottom hinge of the door. When closed, the hinge pins may be removed, but the door will remain firmly in place.
