Nite Ize Figure 9 Carabiner Rope Tightener, Large Aluminum Rope Tightening Mechanism with Carabiner Clip, Fits Rope 3mm-9mm, 150LB Load Limit

I bought this wee thing to act as a cord tensioner of my shade sail. Does the job really well (so far) Easy to use, instructions are pretty clear. At the moment it's holding the entire tension of the sail with just two winds of the cord. I think the body is made from a high quality plastic/nylon, with a stainless steel carabiner gate, but it does the job. Going to buy at least one more, maybe two, as there are lots of things I could use it for. It does say Max Load is 50lb, so under extreme gale force winds, I'd probably take the sale down. I wouldn't be using it anyway.

it's a genius design and works really well. very happy. get some.

Kept with a length of para cord in my Bergen. Handy for when you need to improvise and tighten up a poncho or throw up a washing line! Easy to use and lock off. They seem to be quite robust and durable.

Use niteize figure 9s on a variety of tarps both for ridge and guy lines. In 70mph winds when the rain is horizontal, retensioning lines quickly is pleasant! The small carabinered figure 9s work well with 2.5mm dyneema (Amsteel and Hensteel) which is notoriously knot adverse and paracord. I attach to an Amsteel ridgeline using narrower diameter zingit loops so the niteize can be repositioned easily.

Very strong and well built carabina. It's also possibly a bit large for my needs but thats not related to my satisfaction. I will use this and have already tested for using it on my tarp line. Its light and the use is marked on the carabina in white to show clearly how to wrap cord onto it. Would recommend.

Good for the money, will come in very useful, light weight,

Whenever I have something on my car roof I use these. From kayak to suitcase to pram buggy.

great when you dont have time for knots or need to setup / take down quickly.
