Hardware for a bifold door includes stiles and rails fittable along the edges of a flat panel to form a door and four identical corner blocks for interconnecting the stiles and rails. Each corner block is generally rectangular and fits into a U-shaped channel in an adjacent stile and the U-shaped channel in an adjacent rail. A single hole extends through the block parallel to the stile and closer to one edge of the block than the opposite edge for receiving either a pivot or a guide, depending on the block's location on the assembled door. An orientation indicating marker on the exposed face of the block permits the four blocks to be identically oriented. When assembled to form a pair of doors, pivots are inserted into the holes in one of the pair of doors further from the edge of the door and guides are inserted into the holes nearer the edge of the other door to provide lead-off for smooth closing of the doors. |
