Fire doors should be kept closed at all times – a door closer ensures that the door will mechanically close automatically after it has been opened.

Most closers feature dampers which offer a level of control over the force and speed at which the door closes. This cushion is especially crucial on particularly heavy doors. Correctly adjusting the closure speed can prevent an injury to a small child or a less physically able person; in fact, anyone who is unable to move quickly, even…

A latch bolt is the part of a door that keeps the door from coming open. In order to be a latch bolt, the item needs to slide into place. This separates the latch bolt from chain locks or hooks, where the fastening mechanism is simply placed in a holder. The actual bolt may be in any number of forms, from a standard door knob fastener to a deadbolt. Latch bolts are one of the oldest forms of door-securing technology and are still very common.

Bolts were used as a way to keep doors…

Tweezers

When a key breaks off in the lock, most people go right for the tweezers. Your main concerns should be the thickness of your tweezers and how far the broken key is in the lock. Most tweezers are inappropriately sized for this task and will just end up pushing the key farther into the keyway. Make sure that your tweezers can open wide enough to fit around the key, but not so thick that they cannot fit along the sides of the key.

Due to the warding on most keyways, your…

Make sure that your key fits. Slide the key into the keyhole of the outer doorknob. If the key will not fit, flip it…

Door chains give you some protection when you need to open the door. More importantly, they give you a few vital seconds whereby you can slam the door shut should an intruder try to force their way in. For a small investment, a door chain adds an additional layer of home safety and security. It’s important, though, not to let them give you a false sense of security though. They can’t take the place of quality deadbolts and strong entrance locks.

On the other hand, deadbolts are widely considered to be stronger and harder to pick than latchbolts. One of the main disadvantages of a latch-based lock is its potential accessibility based on its positioning. For example, if there’s a nearby window, a burglar can just break the window and then reach inside and turn the doorknob to get into the house.…
