I love these Koplin Rhino Grips. These are perfect for hunting and carrying almost anything. They will tightly grip a shovel, hoe, wooden board, etc. I even gripped a 4 foot level a while back while building a hunting stand in the woods. These things are incredibly versatile, and are a snap to mount. I have bought 3 sets to put on each of our Atv’s. I would definitely recommend to others and don’t buy the cheaper alternatives, or you will be disappointed. I will always use this on any future ATV purchases. I especially like the button release. No matter how tight the ratchet grip is, the button will release it’s grip.

Pretty easy to install on my 2026 Honda FourTrax Rubicon Deluxe. There aren't many options for positioning the mounting brackets, so I ended up installing it on the front at a slight angle. It should work fine for carrying gear and gives me some extra storage space. I also like that it comes with both long and short screws. I needed to use both lengths to get everything mounted without hitting the frame. Overall, I'm happy with it and think it will work well for what I need.

These are fantastic. I have used a lot of different shotgun holders on rental carts; but wasn't thrilled with any of them. When I bought my own cart for sporting clays, I was hoping to find something better, and I did. I was able to put two on the side uprights and one on the top crossbar to easily fit three shotguns securely without losing space for rear passengers. The were easy to install. Their complete pivotal gripper allows them to be horizontal even if the mount isn't. They grip the guns securely without any scratches. Worth every penny. My shooting buddies are also impressed. I did not install any bases. Just allowing the stocks to rest on the floor of the cart. Push the mobile claw closed and go.

Before buying these, I read all the bad reviews. But I liked the concept so much, I bought them anyway. While I did experience some problems expressed in reviews, they are “fixable”. The base mounted solid to my 4-wheeler rack. Just make sure you put a piece of rubber on both top and bottom of each clamp. When packaged, it looked like there were only two pieces of rubber, but when trying to mount them, I noticed the rubber was actually two pieces stuck together. The wobble was caused by the two Allen screws that hold the grip together being loose. Tightened them a little bit and the wobble was gone. The pictures of broken bases were caused because a metal plate was not used on both top and bottom( That’s why you get FOUR). A little W-D40 sprayed on the claw hinge works wonders. To open the jaw ,when they are holding something, I found if you squeeze the clamp with one hand when you push the release button, it opens easily and without issue. They work perfectly with my crossbow, which was the main reason I bought these. I also used this with my rifle, which has a heavy bull barrel, and they worked great. Went on bumpy trails at 15 mph and nothing moved. They haven’t moved since I mounted them. My 4-wheeler is trailered everywhere on trips. So the clamps get all the road grime and ten miles of dusty road to the deer lease and haven’t failed. While the coldest temperatures I experienced with these is 20 degrees, they worked fine. These are made of plastic, and realistically, I don’t expect them to stand up against running into a tree, or having a large vine snag my rifle or crossbow while riding down a trail, as I am not that careless with my firearms. Nothing out there is “bulletproof”, but these work great for my needs. I would have given them five stars if I didn’t have to tweak them. ##Update##—January 2022– Just order another set. First set I ordered still works just fine. Made it through four hunting seasons and off season chores. The rubber “grippy” parts are starting to deteriorate, I think because I sprayed the ratcheting mechanism with a petroleum spray lube. I should have used a graphite lubricant. Got four good years out of them. Worth it to me. Probably would still be just fine had I used the proper lube. Going to use new ones for guns and old ones for tools(work). They are easy to swap, with just the pull of a pin. Still would highly recommend these!!!!

perfect fit. I really like the rachet on the grip it makes it easy to attach my gun and my crossbow.

Initially I thought these were priced a little too high, but they worked out perfect for my needs. Relatively easy to mount and the mechanism to lock and unlock works great. They fit a variety of different tools and other things going from very wide to small with the locking mechanism. Would highly recommend, great quality!!
