Spring-hinged doors conveniently open, close and latch on their own, and are appropriate for all types of settings including indoor, outdoor, home and commercial. Spring hinges are not difficult to attach to a door and just a handful of basic tools are required. Once installed, the tension on spring hinges can be adjusted to create the desired force.
Position the leaf of a hinge along the inner edge of the door with the pin barrel knuckles facing the side of the door that will open in.
Secure the hinge to the door, using the screws that came with the hinges and a screwdriver. This will be temporary.
Trace around the hinge with a utility knife to score the wood. Use several strokes of the utility knife to create deep cuts.
Unscrew and remove the hinge.
Dig out the space of the hinge leaves (within the score lines), using a wood chisel. Starting in the middle and working toward the score line, hold the wood chisel at an angle and remove slivers of wood until you reach a depth that matches the thickness of the hinge leaves.
Re-screw the hinge in place, using the screwdriver.
Close the door and locate the adjustment slot on the top knuckle of the hinge's pin barrel. Three small holes are within the slot.
Insert the tension adjustment lever that came with the hinge in the right-hand hole. Move the lever to the left until that hole is in the centre.
Insert the tension pin that came with the hinge in the hole that is to the right of the lever. Let up on the tension lever until the adjustment pin hits the right side of the slot.
Open and let go of the door to test the force. Repeat this process, if necessary, to increase the force.
