ABSTRACT:
A perimeter clip is made of a single piece of sheet metal and includes first and second legs that are bent at approximately 90 degrees with respect to each other. The first leg is for engaging the vertical leg of a wall angle. The second leg is adapted to receive the head or bulb of the runner. The first leg includes an upper portion and a lower portion. The upper portion of the first leg forms a back plate that is displaced from the plane of the lower portion, with a generally horizontal ledge connecting the upper portion to the lower portion. The first leg has a tongue or tab that is displaced from the plane of the remainder of the lower portion so that, when in place, the vertical leg of the wall angle is held between the tongue and the remainder of the lower portion. The upper portion of the second leg comprises an inverted, generally U-shaped member, the open end of which forms a trough that supports the lower surface of the bulb of the runner.
