The Fast Cap Hinge Repair Kit is a help for fixing European style cabinet hinges that have failed or torn out of the hinge cup. To use, place the damaged hinge back into the hinge cup and hammer it flat if it's bent. Then, peel off the adhesive backing and position the Hinge Repair Plate over the back side of the damaged hinge. Press down firmly and secure the plate using the included screws, and then reattach the cabinet door.
