Clamping Range
The clamping range of the BoxBolt connector is the combined thickness of the steel being connected and the steelwork being connected to. Each diameter of the BoxBolt connector has three overlapping lengths designed to accommodate a wide range of material thicknesses. If your clamping range exceeds those stated above, special lengths are available.
