A high strength multi use rope grab


The innovative Sterling Bound Loop Prusik(BLP) consists of 8mm Prusik Cord sewn into either 40cm or 55cm loops. The stitched connection is covered with heat shrink tubing allowing the carabiner connection end to be pulled up snug around the carabiner. This keeps the connection point located near the spine of the carabiner (the strongest point) and prevents the prusik jumping up over the becket of a pulley during a dynamic event (as can happen with conventional ‘tied’ prusiks). Sterling BLPs are perfectly matched to the standard sized prusik-minding-pulley and can be used together (one 40cm and one 55cm) as a ‘tandem prusik belay’. Lengths are also colour coded for easy identification – orange for the short and purple for the long.

Other features of the Bound Loop Prussik include:-

  • excellent for any interface in hauling/mechanical advantage systems
  • 8mm Prusiks offer the greatest purchase on 11mm rope
  • BLPs are very strong yet will not overload a system; the prusik will slip under excessive load
  • BLPs negate the need for any mechanical rope grabs or ascenders in wilderness rescue kits.
