## Description

GM CLIMBING 18" / 24" 8mm (5/16in) Pre-Sewn Prusik Cord / Loop Specification Length:18 inches / 24 inches ( the length of loop when flat pull ) Diameter: 8mm / 5/16 inches Material: Polyester Strength: 24kN / 5400lb Assistance in ascending a rope Process capture in hauling/dragging/tensioning System Back-up for belying Tandem rappelling Self-rescue in emergency ... You could find it a super versatile gear in you rack whether you go for rock climbing, tree climbing, mountaineering, caving, or rescue / hauling system set-up, etc. Compared to mechanical grab, Prusik cord is much lighter and more compact, taking little space in your rack. It also does almost no damage to host rope and could work in both directions during application.

Review: Fait son office pour assurer en tant qu'étrangleur une longe de maintien d'arboriste. J'utilisais la version 6 mm, jamais eu de soucis, néanmoins je préfère augmenter le diamètre afin de me sécuriser un peu plus. Ne pas utiliser pour la descente car la matière chauffe très rapidement en cas de forte friction, a ce moment préférez une cordelette en aramide.
Review: Ottima qualità

## Questions & Answers

**Q: What would be the swl (safe working load) for this loop?**
A: Per tag on the loop 500 lbs . MBS 4500 lbs

**Q: Why use this over an eye to eye splice? Can you use a tending pulley with these? Prusiks are hard to unlock under load without one.**
A: If your prussik is under load then you need to unload it some how.  Yes you can use a prussik minding pulley with one.  I chose these as they are easier for people to remember what they are for and you don't have a knot in the way when you wrap the prussik.  We're primarily using them as a brake in the 3:1 system and to attach the mid-line pulley to the rope.  After setting up the 3:1, or "Z" rig, we pull the mid -line pulley which is behind the brake prussik and the minding pulley.  At the end of the haul,  when the two pulleys meet, we set the brake prussik, and slide the hauling prussik and pulley down to capture another stretch of line for hauling.  When that prussik is set,  a pull on the line relaxes tension to the set brake prussik.  The belayer either loosen the prussik or the prussik minding pulley slides it down the rope. If your ropes are icy, muddy, or wet prussiks may not be ideal and the problems must be solved another way, such as a second belay line, and anchoring the hauling pulley with knots to the section or rope to be hauled.  Good luck.  JH

**Q: Can you tie this in a schwabisch knot and stuff like that or does it only do prusik knot?**
A: You'll want a cord with a loop on each end or you'll want to tie your own loops.  This works only for Prussiks.  There is a good U tube video on the schwabisch knot.

**Q: Does a typical screwgate climbing carabiner go into the pre-sewn loop? Sorry, noob climber here.**
A: Unless you're using it in the basket configuration,  it's not strong enough. Needs at least 23 KN rating end to end to be considered strong enough
