Businesses in the locks and hinges category supply hardware used to secure, open and support doors, windows, gates, cupboards and other fittings. Products may include mortice and cylinder locks, latches, bolts, padlocks, door closers, handles, hinges and associated screws or fittings. Some suppliers focus on domestic use, while others stock heavier-duty or specialist hardware for commercial premises, public buildings and industrial settings. Customers can expect advice on choosing products to suit the type, size and material of a door or fitting, as well as the level of security and frequency of use required. Depending on the business, services may include measuring, key cutting, supplying replacement parts and arranging fitting or repairs. Some firms sell directly to the public, while others primarily supply tradespeople, property managers, builders and maintenance businesses.
