GM CLIMBING 8mm (5/16") Prusik Loop Pre-Sewn 18 inches / 24 inches

 Tested 2 after 6 months of use and they sheered at the stitching at 17.7kN & 17.4kN. These loops are rated at 20kN new. Both loops were bought at the same time. I'm going to buy a couple more and test them fresh out of the package and see what results I get and whether the 20kN rating stands up.Testing done with a Rock Exotica Enforcer and a ~98:1 manual haul system.

Bought this because of the reviews. Looks great. Never seen this brand other that here on the Amazon.But, the description explained that it is CE and UIAA rated Prusik loop pre-sewn. I can find nowhere on the packaging or the item itself that backs up this claim. It’s my experience that if this claim is made you can find it displayed on the equipment itself as well as the packaging. Two stars because it will make a great equipment sling. Went to their web site to see if it the claimed certifications were further explained there and it’s “under construction”.

I have inspected these and compared them to NFPA certified prusiks/gear, and see absolutely no difference between the two except cost. As a member of a FD LARRO Team, they're BIG on Certifications... but for my personal gear (and to save a few bucks) these more than fit the bill and meet all of the relevant safety requirements. KUDOS to GM Climbing for making quality / value gear. I will be buying more from them in the future.

This is great for what I need it for but be warned. The breaking force of the whipping is 4kn. Not a typo- 4kn. That is 900lbs. The cord is rated for 4500lbs but a chain is only as strong as it’s weakest link. The whipping is all that makes this a loop and not not just 40” piece of rope. If you are planning on using this for anything more than 900lbs it won’t work.

So far, this little loop of cord does the what it's title suggests. I have not used it enough to rate wear and tear. The rope seems to be made of a sturdy and durable climbing grade material. Using it on an 11mm climbing rope, I found that the shorter loop gives me a 3 wrap prusik with just enough lengh left to clip in. The longer loop gives me a 3 wrap prusik with about a foot left of cord to clip in. The rope is a bit stiff, but this might change after more use. You have to make sure to properly adjust the knot and pull it tight before attaching anything. I'm also unsure if the plasic covering near the end of the loop is supposed to be left on. Taking it off would make one continuous loop with two ends sewn together.

Good quality. The shrink wrap over the sewn area is good protection, and that section can be slid back and forth to change the loop size.

Fairly new to climbing / Rappeling but bought this to use as part of a photo shoot and after learning how to tie a prusik knot this thing held up quite well during the shoot but did bind up once where we couldnt undo it but im sure that is the result of user error. Once we moved the knot below the figure 8 it worked flawlessly!

I bought both the 18" and 24". Great quality and durable. Always take care of your ropes. I store them in my climbing bag inside a weather proof tote. I've used them climbing, exploring mine shafts, tower climbing, and even to secure a tool while working at heights, and yes, there are many other ways to do that. Both are great, but I prefer the extra length of the 24". Keep it safe and always triple check your gear.
