ProX XT-HINGE Pack of 4 Conical Tube Ground Support Post towers Male to Male Hinge Joint Fits F31 F32 F34

A pack of four male-to-male adjustable hinge joints for 2 inch conical truss, sized to fit F31, F32 and F34. Four is the number a square truss needs: one hinge per chord, so a single pack turns one joint in a ground-support tower into a hinge. That is what lets a roof system fold flat on the ground, get pinned, and be raised as an assembly rather than built at height.

They are equally useful away from towers. Set the angle, pin it, and a hinge block makes shapes a fixed corner cannot - arches, raked legs, non-square goal posts - out of the same standard lengths already in the truck. Each hinge is machined from 6082-T6 aluminium and ships with two locking pins and two pin clips, so nothing depends on hardware you have to find yourself.
