ABSTRACT:
A generally L-shaped coupling plate having an arcuate mandrel at the junction of two generally rectangular tongues is united with a notched out channel by inserting the first tongue into slots defined by the web of the channel and opposed ribs spaced apart from and parallel to the web, bending the notched out portion of the channel around the mandrel, and inserting the second tongue of the plate into the slots of the bent portion of the channel as it approaches the plate. Barbs on the edges of the plate dig into the channel to secure the union of the two pieces. The channel may be painted before being bent around the plate so that a predecorated rounded corner runner may be installed at the intersection of two partitions.
