An aluminium flush bolt security door lock is a type of locking mechanism commonly used on the inactive leaf of a double door. It is designed to secure the door in place by sliding a bolt into the door jamb or floor, and it is flush-mounted to the door so that it does not protrude when not in use. The lock is made of aluminium, which makes it durable and resistant to rust and corrosion.

The flush bolt is typically installed at the top or bottom of the door, and can be operated manually by turning a knob or using a lever. The bolt itself is usually made of steel and is between 6 and 12 inches in length, depending on the height of the door. The bolt slides into a receptacle in the door frame, securing the door in place and preventing it from being opened.

These types of locks are commonly used on double doors, such as French doors or closet doors, to provide an additional layer of security. They can also be used on single doors as an alternative to a standard deadbolt lock. Overall, the aluminium flush bolt security door lock is a simple yet effective way to secure your doors and keep your home or business safe.
