Show Solutions 20.5" x 20.5" Hinged Plates (old sku# ST-2020-HP)

A set of hinged plates for 20.5 by 20.5 inch box truss, previously catalogued as ST-2020-HP. They bolt between two truss lengths on the standard plated bolt pattern and let the joint pivot rather than lock at a fixed angle, which is how folding roof legs, raked headers and adjustable arches get built out of straight stock. On a ground-support roof they also let a section be laid over during build and brought up to angle once the pickup is made. Sized specifically for the 20.5-inch profile.
