Solid SxS Jack mount
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

Heavy Duty. Good for clamping and resists vibrational movement as 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.

Heavy duty but a little too stiff.
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.

Great Idea but broke
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.

Great for a 20oz tumbler atv/utv cup holder ( extra parts needed read review)
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!

Way to stiff!
Had plans on using them on small fire extinguisher. They are extremely stiff with little to no stretch at all. I work with my hands for a living and have strong hands and had a hard time even getting the strap open. I was even thinking of using one on my four wheeler to hold a shovel but I couldn't imagine trying to open or close it when cold. If you need to use the last hole like I do for the fire extinguisher there isn't enough strap length left to get a strong enough grip on to open or close it. EDIT I held the rubber strap and pulled on it to stretch it in front of the heat vent on my stove. Im now able to use it like I should.

Well built, but....
Well built but typical small fire extinguisher is too big for it. Will use for something else. A bit hard to unpack.

Great value
I did cut and modify these for my application that's why the side ears are missing where they could be clamped down. An excellent value at $14.99 including shipping they work great to hold this speaker that I have it's a JBL charge 5 the straps need to be really stretched out for them to in order for them to work in the beginning but they work well. This weekend I'll find out and see how well it does put the speaker on the hood but it feels very secure

Leider muss ich meine Rezension korrigieren. Anfangs ein gutes Produkt. Montage flexibel und robust aber leider ist das Material Minderwertig. Der Gummi baut in der Sonne massiv ab und wir porös. Letztlich reißt der Spanner beim Schließen des Verschlusses ab. Nicht fürs Fahrzeug geeignet
