Kolpin 21571 Black 3" Rhino Grip, 2 Count (Pack of 1)

On first look I thought the straps were too stiff to work properly. After installing I found them to work well for mounting a Jack to my Can Am. It’s solid and I believe it will suit the use well

Most important part with these is that they have more than enough heavy clamping strength to prevent any up or down movement. I used this for my boat fire extinguisher to hold mid-air. While trailering, that can be very useful.If i had to pick a downside, I'd say the clamp might be a tad too big in the back. Should ideally by longer upfront than in back, but this is a very minor thing.Still hands down best clamps on amazon.

I am using these to secure an AR15 and Mossberg 590A1 in a 2018 Ram 1500 pickup. They hold the guns securely but the retention strap is very stiff and hard to release. Not really a problem, just be aware you need to mount them in position that gives you some leverage on the strap. Very sturdy and well made, won't wear out like Velcro.

I purchased these back in December 2021 5 months later i went to latch one of the 3 i have mounted and the rubber broke. These are mounted on top of my flat bed truck and used to secure loading ramps down to the bed when in transit. They look great and work awesome!, however the rubber is not reliable at least the one i have. Koplin was good and replaced it no question asked so that was awesome. Hopefully it was just a lemon out of the bunch.

I bought this to hold a 20oz tumbler cup. I was looking for a quick release clamp but no other company made one that would fit a tumbler so I improvised!I did have to buy smaller light bar brackets in order to mount this, I used one of the two that came to mount it on as you would if you were mounting a fire extinguisher.So far I’ve risen nearly 300 miles with this and in West Virginia in some serious rough terrain and on the road up to 50mph nearly. Of course if you are riding hard it’s a good spot to stick your cup for a bit of a trail you will want to make sure you press it in tight!I have mine set the widest it can go and I did have to sort of break it in over a few uses. Now it is great!

The concept of these is great, but the execution is not. The straps are so stiff, that only the first 3 slots are useable, so you can’t easily cinch things down tight. If they were made of a softer material, they would actually be a lot more useful. They are easy to mount and hold securely, but not being able to fully utilize the smaller dimensions, due to the stiff straps, makes things flop around too much.

When these say 3" max, they mean it!I bought these to install a fire extinguisher on my Rzr. The one I purchased at home depot was 3-1/4" and there was no way i was getting the mount around it. I bought a diffrent one at 3" and was tight but fit perfectly.These are very durable almost to the point of hard to get them to open. (Which really is a good thing)

These are just way to stiff. I wore my hands out just getting them open. I then (attempted) to secure a shovel and axe on two separate mount and after giving it all I had I was able to get to the 3rd hole and it would NOT even hold a full sized axe hand or a standard shovel. When I finally did get it to the third look the first loop now looks like it is about to snap! These are complete junk. EXTREMELY DISAPPOINTED and will be returning. I will say one nice thing, they do look great! Lol
