They are like many more expensive versions at a reasonable price!Fits my etrack just fine.To get more tie points per rachet-strap, I used a few of these to allow me to cross strap a piece of equipment to the e-track. works great.Looked great until I went to use them. One will not stay latched in.These things are great if you have any basic fabrication skills and access to welder. You can weld them to something (or a mounting plate you could then bolt) to create any e-track accessory your mind can dream up. I have used them extensively in a cargo trailer to bunk house conversion. It allowed flexibility of where to place items so things didn't have to be permanently fixed to the wall.Welded these on to permanent Erickson wheel chocks, now with the help of E-Track, I can place chocks wherever I want on the trailer.To be used in a race car trailer to secure two nitrogen tanks so load won't shift during travel.Easy to useExactly the product I needed to fabricate my own E-track pieces. After doing an enclosed trailer toy hauler / rv I needed some pieces that weren’t available. I heavily invested in floor and wall E-track so I could make my setup modular and adaptable to different scenarios. My bolt bins for racing he previously been screwed right to the walls which I hoped to avoid. I welded two of these connectors with 3/4” steel tubing between them. They connected to the wall E-track and the bins ratchet strapped to this. Everything is solid as can be and removes in under a minute. Everything commercially available starts with these pieces and then has hooks or whatever welded to them. I have plans for aluminum shelving that will be bolted to mounts welded to these fittings. So many possibilities. I bought the 50pc pack because I know I will find a use as time goes on.The hole to fit a strap is too narrow. Must of straps have a double layer sewed ending wich won’t fit in these.Very small contact area , however has not popped under load yetVery pleased with the value and quality of the product.
