This endless ring is a flexible anchoring point for a professional working at height but also for a zip line start and finish, to hang an object or to hold one from a possible fall. Solid as an Ardennes draught horse, this polyester sling is easy to place thanks to a pretty lark's knot. It is of course advisable to read the instructions before use. It is possible to have coloured rings on order at La Corderie (Brussels).
