Cabin Hook Lock A cabin hook lock is a good option to secure gates for gardens and also keep doors open. It is made up of two components of a hook that can be attached to a wall and an eye that attaches to the door. It is usually made of steel and is protected from corrosion to stop rust staining. The cabin hook should be placed as far as possible from the hinge. This will reduce the force applied to the fixing and avoid a stress on the hinges.
