The beauty of the IA Rig System is that not only does it provide a solution for a start-up facility, but there are so many options for attachment, and additions, that this will fit almost any other system known to man. However, please note, our IA Rig system has been purposely over-engineered with 75mm x 75mm Box Steel. The walls of this mammoth are 4mm thick, well above anything else we can see on the market today. To complement that, the pins on our J-Hooks and accessories have a 19mm solid steel rod, that is recessed through the plate. This is the only safe way to build a J-Hook in our minds.
