EQUIPTZ 6 inch Spring Clamps Heavy Duty - 4 Pack Large Plastic Clamps for Woodworking, Crafts, Backdrop and Pool Cover with 3 inch Mouth Opening - Rust Free Spring Clips with Non-Detachable Jaw Pads

These 3-inch spring clamps are excellent quality and far exceeded my expectations. They have a very strong gripping force and feel solid and durable right out of the box. Each clamp is well made and sturdy, not flimsy like some smaller clamps can be. Made with tough plastic that is weather proof.What I really love about these is the jaw design. The jaws have a slight rotation, which allows them to easily accommodate different shapes and thicknesses without slipping. The non-detachable jaw pads are a big plus as well because they stay securely in place and don’t pop off during use. The clamps are not to heavy and weigh just about right for its size.I recently used these clamps to hold down a tarp around my dragonfruit plant, and they performed flawlessly. Even with heavy wind and rain, the clamps kept the tarp firmly secured without loosening or shifting. That alone speaks volumes about their gripping strength and reliability.With 20 clamps in the pack, they’re incredibly versatile and useful for a wide range of tasks; from outdoor projects to crafts, tarps, and photography setups. Overall, these are high-quality, dependable clamps that truly get the job done. I would definitely recommend them and will be using them often.

One of the best clips in my shop. Sturdy, and functional.

Only used them once so far, but they worked very well. They don't skip around, the clamps swivel to make contact, and the springs are strong and sturdy. I'm happy with them.

Decent clamp,works good

Great grip strength and the assortment is wonderful. Very durable. We use them at the campsite and at home. So happy with this purchase.

Very strong and work very well.I attached these clamps to a very large tarp to protect the side of my RV, which had an RV cover, which was disintegrating anyway these clamps held that tarp onto my RV and the wind was blowing like crazy and it still stayed attached. I already ordered another set. Plus, I’m going to order another set to have on hand.

Very strong clips

If you go to a hardware store, clamps sizes indicate the max width that the "mouth" of the clamp can open. This helps you understand what size you need (based on what you are trying to clamp). These EQUIPTZ clamps use the total length of the clamp assembly as the sizing measurement. This is a mostly worthless way to measure a clamp, but it sure does make it *seem* like a good deal for what you are getting.I ordered the 4" clamps because I needed clamps that can open up to 4" wide to secure a pool cover on an above-ground pool. However, what I actually received was a set of clamps that can open up to 2" wide ... but that are 4" long. So they are actually 2" clamps, which don't help me at all with my pool cover.Also, the amount of pressure required to fully open the clamps is significant. A person with grip or hand strength issues of any kind is unlikely to be able to use these. Also, they probably shouldn't be used on anything delicate because the pressure exerted by the closed clamp is tremendous.I will keep them for other projects, as you really can't have too many clamps on hand. But I really do not like the sneaky / semi-dishonest way these clamps are marketed. I will not purchase anything from this brand in the future.
