Door hinges are crucial pieces of door hardware which are used to both hang and open/close a door. The ball bearing style of door hinge is a durable option which consists of steel ball bearings positioned between the hinge knuckles. Whilst standard hinges can often deteriorate over time resulting in loud squeaky noises, the steel bearings within the ball bearing hinge ensures a much quieter and smoother motion when opening and closing the door. Most internal doors will require two hinges to function properly whereas doors with added security functions will typically require three or more to help prevent forced entry. When installing fire doors, fire rated hinges will need to be used and customers are advised to check that their hinges meet the required fire safety standards. Available in a variety of finishes, there are plenty of choices to suit your needs.
