Global Truss ST-UJB/C-F14 Corner Block Half Coupler

A corner junction block is what lets an F14 run turn a corner cleanly instead of being mitred and hoped for. The ST-UJB/C-F14 is the half coupler that fixes a truss chord into that block, and there is one per chord, so a corner needs several.

It takes an M4 x 12 mm bolt and is sold individually rather than as a set, which is worth knowing at order time: count the chords on the corners being built and order to that number, not to the number of corners. Global Truss part number F140131.
