Not sure how I’d never come across this product before, but today was the first time I’ve seen these…

I already have both the ratcheting and vise style corner clamps. Even made a set that’ll work with traditional bar clamps. But these spring loaded ones look like they could be convenient.

My only thought is that they probably don’t offer much in terms of actual clamping force. And are also kind of limited in the wood size they can accommodate (.85”).

Yet, even if they’re mediocre, I’m thinking they could still have an application. Being an extra set of hands to get the workpiece quickly and easily clamped. To where it makes strapping on a ratcheting style one a heck of a lot easier.

One particular brand is selling them for like $17. And they come with inserts for 60, 90, and 120 degrees. Which is a functionality that my other corner clamps can’t match.

Anyone have thoughts or firsthand experience? Really been trying to limit my purchases from china.com, but these have me intrigued.

I was given a set of these for Christmas. I haven’t used them yet and probably never will. I did pull one out of the box for 10 seconds. You might as well just grab a Potato Chip Bag Clip instead. It would have more hold strength, better quality plastic, and it would keep your chips from going stale, which would make it more useful they these fisher-price corner clamps.

I’ve got Wolfcraft versions of them, and I’m not sure where they’re made, as they just say “Made in the EU”, but they are a German company, for what that’s worth. They feel fine from a quality standpoint, nothing special, nothing super cheap either. Your thought about clamping force is pretty accurate for thinner stuff. It doesn’t provide much, but can help to get them aligned eventually. With thicker stock, it does better because the spring is more compressed, but then it’s also heavier so that sort of counteracts it as well. I find them fairly difficult to use on 3/4” stock, as you have to get a pretty good squeeze on them to open the jaws wide enough. Then you have to fiddle with them to get the corner block in the right spot, and get things lined up and square, etc.

I rarely use them, because I don’t like them. I find them too fiddly and annoying for what I do, and I don’t often have a need to clamp up corners like that, as I usually have some form of joinery that will do that alignment for me

Thanks guys. I could accept the clamping force being on the lighter side. If they were quick and easy. If you have to fiddle with them AND they’re super weak? Sounds like a hard pass.

Several versions on Amazon. Picked up a pair but have not tried them yet.

Picked up a set, dirt cheap and they work for work holding/positioning and not so much ad clamping/pulling together. I would not speculate on life span.

I definitely view them as just holders for a second pair of hands than anything else. For that, they work out ok, but not much more

Lol. Now I’m reconsidering. As I was thinking they’d serve this exact purpose.

I have a set of Wolfcraft version. Purchased them on sale to have on hand in case a situation came to use these. Only used them once. Was difficult to pull back with the springs it has. But worked nicely once clamped.

Have your say...
