What would be the swl (safe working load) for this loop?

Per tag on the loop 500 lbs . MBS 4500 lbs

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.

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

Can you tie this in a schwabisch knot and stuff like that or does it only do prusik knot?

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.

Does a typical screwgate climbing carabiner go into the pre-sewn loop? Sorry, noob climber here.

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

Very nice and great buy!

Really nice cord for safety. It appears to be made very well with stitching and overall design. I feel confident that it will perform very well under a load. Size could be a little more generous but it functions very well. Tying a prusik knot is very easy and hold very well. I believe it's a lot of value for the money spent and a nice addition to my climbing / rappelling gear. Would certainly purchase this again.

If you are saddle hunting and use a me handicap ascender please buy one of these

Works very well. I bought it for an additional safety for my ropeman 1. On my tether as well as my lineman belt. We can never be too safe. I was saddle hunting before it was cool back around 2003. Saddles have changed a lot since then. Ascenders are mechanical and can break. Take an additional 10 seconds and attach another prusic.

Tough & affordable loop, but further testing needed.

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.

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

Decent prusik for the money. Full disclosure... I have not rappelled with it yet. Just bought it for an emergency decent/escape/rescue kit. It seems well made with good stitching. A prusik is not a primary brake mechanism in most cases, but more of a fail safe used as a backup to your belay device. I think this one is adequate for that purpose.

Works great; might be long for some applications

We bought this for a basement hoisting job. It worked great, but was a little longer, we found, than we needed. If you're hoisting with your blocks close together, you might want a 13" prusik. We made it work, and it got the job done.

必要最低限。

定格22kN、ざっくり2tfの静荷重で壊れるらしいので、長期安全率２に衝撃荷重12Gを前提にすると大体186kgfまでなら許されそうな感じなので、余程がなければ使えるんじゃないかなぁ。
