A butt hinge is made up of two leaves with three or four knuckles as well as a pin, which connect to create a barrel that is curved, called the knuckle. The barrel or knuckle is the pivot point for the hinge. It is typically connected to the leaf using screws.

This will prevent friction from wearing down the knuckles, and will keep them running efficiently. Some butt hinges reduce friction by putting the ball bearing between the knuckles. These hinges are ideal for doors that are heavy-duty and high-use. They are also available with a pin fixed that is perfect for doors that are secure and cannot be opened with the removal of the pin. Other types of butt hinges include a plain bearing with grease that reduces friction permitting the hinge to move with minimal force. These hinges are best suited for applications that require less force such as cabinet doors. They are also available with spinned ends to ensure that the pin stays in the correct position. Butt hinges are used in commercial and residential environments. For instance, they are used in medical and research facilities to shield patients from radiation and neutron contamination, as well as vault doors and security systems.

They also allow the door to open and close smoothly around the pin or axis that connects the two hinges and distribute the weight of the sash evenly for better performance over time. Similar to other hinges Butt hinges are also available in a range of sizes and load-bearing capacity to accommodate different door size and weights. The application and desired level of durability and performance will determine the type of hinge that is chosen.

For the majority of applications using standard uPVC will require x3 of hinges. The top flag hinge should be placed 150mm above the top edge, and the middle, bottom and outer hinges must be evenly spaced between them. To check the correct position of the hinges, a sash of a door should be shut and raised to its full height and you should be able see the hinges at their full length when fully raised.
