The BoxBolt® Rigging Clamp is a means of attaching an anchor point to Hollow Structural Sections (HSS) and other structural members when access is available from only one side.
The standard BoxBolt® Rigging Clamp utilizes Hot Dip Galvanized M12 size 1 BoxBolts® and a load ring welded to a custom fabricated anchor plate that allows for Safe Working Loads up to 5000 lbs.
The BoxBolt® Rigging Clamp is easily installed by Drilling a pre-determined set of 13/16” holes into existing steelwork, lining up the anchor plate with the newly drilled holes, inserting and tightening the BoxBolts® to the specified torque values. There is no more need for site welding, tapping, or strapping.
Note: Blind Connection rigging and lifting points can be individually designed for each application and carry a wide range of load capacities (Up to 30 kips) Although the manufacturer guarantees the Safe Working Load of the BoxBolt® Connection, we are not responsible for the structural integrity of the existing steelwork. We recommend that a Licensed Structural Engineer be consulted to establish the capacity of the existing structural member.
