Abstract: A replacement door hinge that facilitates the repair of a damaged door slab is provided. The replacement hinge includes a jamb side that is essentially the same as a conventional hinge to allow traditional mounting into the recess provided in the jamb for hinges. The slab side of the hinge is formed by a pair of opposing hinge leaves that are received on opposing sides of the door slab and include inwardly facing spikes and at least one or more countersunk screw holes to allow fastening therethrough to use screws in combination with the spikes to firmly engage the door slab. The leaves include a ratcheting retention system that engage at the edge of the door slab to allow installation onto door slabs having varying thicknesses while holding the front a back leaves together to form one unit that wraps and reinforces the door slab.
