Show Solutions 4' long, 12" x 12" box truss with grade 8 bolts

A 4' (48") section of 12" x 12" Pro Series box truss, supplied with grade-8 bolts. Main chords are 2" outer-diameter 6061-T6 aluminum at 1/8" wall with 1" outer-diameter diagonal bracing, and the end plates follow the industry-standard plated truss bolt pattern, so it ties straight into existing 12-inch box truss inventory. Four feet is the working length for short spans, tower cross-members and filling out a lighting grid, and it is light enough for one tech to place without help.
