How Does a Door Security Chain Work?

Degol Tell You : How Does a Door Security Chain Work ?

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.

For door security chains to work to best effect you must fit them properly. The chain fixture has to attach to a stationary surface, usually the door frame, and the slide catch to the door. The slide catch must be close to the door’s edge. If it’s too far away you won’t have freedom to attach or detach the chain. If in doubt get someone to fit it for you. It’s a quick job, but it is important to get it right.

There are alternatives to door chains, and those are the somewhat stronger swing bar door guards or door restrictors. Like the door chain, door restrictors also only allow the door to open a little way. The difference is that they are significantly stronger than the majority of chains. You will often see these fitted to doors in motels and hotels. They won’t scratch the door either, as there’s no chain swinging and tapping against the door each time you open it.
