At the heart of the system is the unique, variable self-orientation mobile anchorage sleeve (Patent Pending) which gives trouble free passage through the intermediate or corner anchorage. The user simply selects the approximate angle at which to work and attaches a karabiner to the corresponding hole. The mobile anchorage will always remain in the correct position and self orientate to pass through the intermediate. This enables the user to work either side of the line and pass through the whole system without disconnecting. When used in conjunction with our ladder system, ladder bracket and permanent anchor points we can design a seamless attachment, from ground to roof for totally safe access.
