Hey TOUGH-GRID, what were the results of your tensile strength test's of your cord? What weight did it hold up to?

Hi Atilla, Sorry I didn't see this question long ago! Must be my old eyes or something. ; - ) There is a range at which our 750lb Type 4 Mil Spec cord fails/breaks. Generally speaking... that is somewhere between 760 and 820+ pounds. Why the range? Well, even though we ONLY sell Mil Spec cord, there are still variations in the yarns that necessitate an honest disclosure about the break strength. In reality... no two cords are ever identical due to variations in the nylon manufacturing process. That said; our cord always exceeds the 750lb minimum break strength... sometimes it exceeds it by more than other times. Thanks, Bill... TOUGH-GRID

You mean when taking it down? I recall average strength. If it won't budge, there's a tangled cord or something.

These cords weigh approximately 20lbs. I will have Amazon update our listing. Thank you.

Yes.I weigh 155 and it bent when I was half way up a 15' wall testing it out.I then straightened it out and welded the tines together at the main shank. It's working great now.I have used it about 10 times. Climbing 10-30 feet. I changed the rope of course.To reach the higher limits I tied a string to a large nut and tossed that over a tree limb and then attached the grapple and pulled it over.Be safe!Roy

It seems to be pretty strong. I stretched it enough to get a good, tight wrap without it breaking. I don't know just how much it would take, but at least I didn't have a problem with it breaking.

Honestly it feels lower in torque in the hand but when I tested it on a bolt highest I got it to was 350 to 380 foot pounds of torque in my opinion it's worth every penny when it comes to light weight and no cord and it lasts about 3 to 5 hours of constant use overall I give it 10 out of 10

1875. And stronger than other cord keepers I've tried. My favorite so far :)

As a 50 foot cord it is pretty manageable. It is the medium duty, heavy gauge wire so it can certainly can get in a tussle if you let it. The heavy duty cords are the real bear. If you are running 15 amps or less this is the cord you want. Anything more than 15 amps you need the next size up. Less than 10 amps, you may want to step down and get the more flexible cord at a higher gauge.

I've got a 50ft heavy extention cord run out. I would not use a light weight household type cord though. -0 temperatures and product has worked fine.

It is kinda thin for a hammock. It would support the weight no problem, but I have had a couple hammocks and the cord was much thicker than this.

I'm using spider wire FluroBraid 30lb, so far it's been pretty good, a couple of wind knots but they're easy to pull apart.

Your best bet is a 16 guage heavy duty cord. Now depending on the lenght of the cord, the manual may recommend a 14 guage. These cords btw, come in different colors.

While not intended for climbing use, I and others have successfully used it to rappel to show that it could be used in emergency situations. However, there are several issues with it; just because it is rated at 550 lb. break strength doesn't mean it always holds that amount; Google "rope strength" and check out "working load," which is much less than breaking strength (most climbers ropes are rated at several thousand pounds breaking strength/tensile strength), also that knots weaken the tensile strength of rope (some knots worse than others, and can reduce the strength by as much as 50%), and people don't count in the "shock" factor which happens when you slip a little or put "sudden" weight on a cord, which greatly increases the weight over the normal weight and can snap it, or consider what might happen if you have the cord wrapped around a sharp or abrasive object, further increasing the risk of failure. In other words, I would advise doing lots of research and being in a situation where ALL you have is 550 cord and you MUST escape by rappelling before you should ever even attempt it. There are a few YouTube vids of people rappelling on a single strand of 550 cord, but it's a huge risk and is NOT recommended. Having tested it myself and knowing how careful I am, I personally am comfortable with the notion of using it in an emergency, but I will try to double/triple (or more) the cord if possible before rappelling. (On a recently aired survival show, two guys used a single strand of paracord to rappel down a sheet of ice, and they were big; I am 6'5/230lbs.). If I had to guess, an inexperienced person rappelling from over 50 ft. over a hard surface on a single strand would have about a 60% chance of survival; decide if that sounds good enough to you.

I replaced mine with a slighty larger, stronger rope - personal preference only - the cord that comes with it is plenty strong and is long enough for almost any application.

I can't tell you specifically what tensile strength is but I can say it is not designed for high-tension applications. The strapping is embossed with a diamond pattern that makes it appear to have reinforcement - but it is just for looks.

Contact them and they will send you a new cord. The 175lb pull is too strong for that crank. I had the beef mine up when it was ripped off its base after the first yime I cranked it. Check my previous post with pictures.

Feels like 10 pounds with cord attached. Both husband and wife use it never a problem with the weight.
