How well do you look after your outdoor spaces and gateways? This Chain Bolt is perfect for a garage door or stable door, acting as a valuable layer of security on top of existing shutting mechanisms. It is easily slid on and off for a simple way to keep your entrances and exits shut tight. When the chain is pulled, the bolt is opened, and then once released the bolt springs back into position - a simple but effective mechanism designed for ease of use. This Chain Bolt has been designed by the manufacturer to withstand moderate outdoor environments. It is plated with zinc; a material which is proven to act as a protective layer on top of metal, negating the potential corrosion which can occur when left outdoors for a long period of time. The metal itself is strong and durable, giving this product an excellent working life.
