These are the Luxury model with snap hooks or Zorber. These are appropriate for clipping in to static protection or anchors with some dynamic load absorbing features like rope or fairly slack cable such as a belay cable on a high ropes course. Zorbers MUST be used if any protection anchor points being used are static (bolts, bolt hangers, staples, steel rods or beams) Zorbers may be omitted if all anchor points used are dynamic (cable, rope, spring loaded anchors).Lobster Claws are a unique, adjustable set of positioning / safety lanyards designed specifically for program high ropes courses. Using the claws, the participant can move from element to element on the high ropes course while remaining securely connected at all times to at least one point of contact. Each "claw" is fully adjustable from 27" fully shortened to a maximum length of 51" fully extended. At the ends of each claw is an industrial snap hook. It requires 2 separate motions to open the gate to disengage it from a connection in order to maintain safety.
