If your front and back doors are not secure, neither is your home. Two thirds of burglars gain entry through a door. If you are replacing a door, take the opportunity to install security doors that are certified of enhanced security.
Wooden Entrance Security Doors
All wooden entrance doors should be of solid core construction and at least one and three-quarters inches.
This also applies to the exterior pedestrian garage door and the door that passes from the house into the garage. Security screen doors provide excellent additional security when equipped with a good deadbolt lock.
Sliding Glass Security Doors
If your sliding glass door is not equipped with hardware that prevents it from being rocked off the track when in the locked position, install a slide-bolt lock at the bottom or a pin. The pin anchors the moving door to the stationary doorframe. Drill the holes and install the pin angled up to prevent it from being shaken out of place.
Caution: be careful not to break the glass when drilling the hole for the pin. As another precaution, install an anti-lift device in the top track.
Security Screen Doors
Security screen doors offer good protection and allow for ventilation. Insist on the following features:
– Ring guard for the single cylinder dead-bolt lock
– Perforated or expanded metal screen to prevent reach-through
– Steel frame installed using non-removable screws or welded in place
Install a single cylinder deadbolt lock and metal flush bolts on the inactive side of French doors and a reinforced strike plate. The glass should be tempered or coated with a burglary-resistance glaze.
Single Cylinder Dead-Bolt Lock
Equip all single- or double-entrance doors with a single-cylinder dead-bolt lock. The bolt should have a minimum projection of one inch and be constructed to foil a cutting tool attack. The bolt should be embedded at least one inch into the strike plate. The cylinder should have a cylinder guard, a minimum five-pin tumbler and should be connected to the inner portion of the lock by connecting screws.
Screw in the dead-bolt’s strike-plate using at least two 3-inch screws that go into the frame of the house and not just the door frame. The throw of the dead-bolt, when in the locked position, is embedded into the metal strike plate on the doorframe.
Double-Door Inactive Leaf
Provide the inactive leaf of double doors with metal flush bolts that embed a minimum of five-eighths of an inch into the header and footer of the doorframe.
Door Viewer or Peephole
Install a wide-angle (180-degrees) peephole on all front entrance doors.
Use non-removable hinge pins or mechanical interlock to prevent removal of a door that swings open to the outside.
