Abstract: A corner reinforcement for tarpaulins has an upper and lower plate connected by two enclosed edges forming a right angle. The reinforcement structure has an open edge that arcs back towards the corner defined by the enclosed edges and has rivet holes fixed along an arc concentric thereto. A rib positioned on the inside surface of the top plate runs along the arc defined by the rivet holes on the upper plate, while a mateable groove positioned on the inside surface of the bottom plate runs along the arc defined by the rivet holes on the bottom plate. A grommet is also provided for securing a rope to the corner of the tarpaulin. The corner of a tarpaulin is inserted through the open edge and its shape is accommodated by the right angle formed by the enclosed edges. The rivets are then fixed in place causing the rib and groove to mate, providing reinforcement to the corner.
