These hinges are ideal for lighter applications such as cabinet doors. They are also available with spin-ends that ensure the pin will remain in place.

Butt hinges come in various sizes and loads to fit different door weights and sizes. The type of hinge that is selected will be determined by the purpose for which it is used and the desired degree of performance and durability. The capacity to bear load of a hinge is based on the force that is applied to the hinge, and the amount of time it is exposed to that pressure.

Using the fixing jig, pre-drill these positions and then screw the hinge plate to the sash so that it is in line with the profile. To prevent damage to either the sash frame or the sash itself, ensure that the screws furthest away from the hinge are secured into the plastic and steel reinforcing instead of the wood. Next, insert the hinge body pin through each of the slots that are used to locate the plate. Attach it using the screws in the same order.
