Add To Door Security

Keeping your entry door secure involves having a strong metal or solid wood door and using the right locks. Also, you need to make sure your door hangs properly and fits well in the frame. If your door isn’t installed correctly, it might not matter what types of locks you choose for the door. Deadbolts and door locks are the most common methods to secure entry doors. There are also electronic door security options available.

Items such as door limiters, security chains, and surface- mounted door bolts are straightforward to install since they are simply positioned on the appropriate place on the door or frame and screwed into position. Items such as hinge bolts, deadbolts, and peep holes require a little more thought in positioning and installation. This is because slightly more involved woodworking techniques are required to ensure that they are installed securely and correctly.

Attaching a Hinge Bolt

Hinge bolts should be installed in pairs as a minimum requirement, one below the upper door hinge and one above the lower door hinge. For extra security a third and even a fourth bolt may be used.

A. Drill a hole into the door edge; its dimensions should be specified by the manufacturer.

B. Hammer in the ribbed section of the bolt into this hole, leaving the smooth domed section protruding from the door edge.

C. Gently close the door to mark the frame. Position the plate, draw a guide line around it, and chisel out to a depth equal to the plate. Drill a central hole to house the bolt.

D. Screw the hinge bolt plate in place, and check that the door opens and closes smoothly. Use the same technique to secure more bolts as required.
