How It Works

How It Works

The Blind Rigging Clamp attaches an anchor point to Hollow Structural Sections (HSS) and other structural members when access is only available from one side. The Blind 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 Blind 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.

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).
