Global Truss ST-UJB/C2-12 Long Coupler 4-Pack for the ST-UJB-12 Junction Block

The ST-UJB/C2-12 is the longer coupler set for the ST-UJB-12 corner junction block, supplied as a pack of four. At 56.7 mm (2.23 in) it is the deeper of the two coupler lengths Global Truss lists for this block.

The couplers are S45C steel with M12 x 25 mm bolts on a 1.75 pitch thread, and Global Truss specifies a 18 ft-lb bolt torque. The four-pack weighs 4 lb. Use the coupler length the joint calls for; the shorter ST-UJB/C-12 is not interchangeable.
