ABSTRACT:
A corner piece for a sheet metal connector system that includes coupling members which have a V-shaped cross section and inwardly turned retaining edges spaced a given distance from the apex of the V includes a first leg which has a width slightly less than the given distance and a length, and a second leg which has a width slightly less than the given distance and a length which extends at an angle other than 180 degrees with respect to the first leg's length. The first leg may be snugly fitted between the apex of a first V-shaped coupling member and the inwardly turned edge of the first coupling member and the second leg may be snugly fitted between the apex of a second V-shaped coupling member and the inwardly turned edge of the second coupling member to join the two coupling members together at the angle. The first and second legs may be identical separate pieces which can intersect and be joined.
