The RGA11 is designed to provide vertical fall protection to operative ascending /descending a ladder or structure and incorporates an attatched shock absorber. This version of the rope grab is for use with 8mm Stainless Steel wire rope only. When used by itself, the RGA11 should be connected directly to the chest attachment of a harness (RGH2/RGH4) via a karabiner. This ensures that the operative is held close to the structure and in the event of a slip the fall distance and loading on the top anchor is minimal.In working conditions it is usual to provide additional fall protection equipment to protect the user when detaching from the device at height (i.e. RGL Range).
