Topic tags/keywords: clamp parallel clamp question

Hey all. I’m trying to decide which size of parallel clamps would be more beneficial out of the 24” or 31”. I’ve got my eye on some 12” and 40”, but can’t decide what I should do about the middle size. For those of you who have both sizes, do you find you use one of the sizes more than the other? If you don’t have both sizes, do you wish you had both, or would have gotten a different size?

I have some of both, I’m not sure which ones I use the most but I have a lot more 24” clamps than the 31” ones.

I use the 24” more than any others, but when you are clamping something wider you need a bigger clamp. Sure you can clamp an 18” panel with the 31” clamps but it is more awkward. Look at what your average panel size is and decide from there. It is not a life or death decision and acquiring clamps is best not accomplished all at once, get the ones you think will get the most use now and down the road you can look at getting some others.

If you get the 31 you’ll have the extra capacity to clamp beyond 24 without the extra length of say a 48. The difference is small so I’d go with the 31.
Good luck in you decision.

Simple answer, both, start with 2 of each then more as $ allows! nothing more frustrating than a clamp thats 1/2” too short.

24’s are my most used clamp, as well. I agree with pottz that if you are going to get some 40” ones, then I’d stock up on 24 and use the the longer ones on the few occasions you need something bigger.

Personally, I think I would skip the 12” ones. Split your budget between the 24” and 40” ones. That should get you what you need. You don’t need every size they offer. I have 50” clamps, personally. No smaller parallel ones for now.

What projects do you use the clamps for? Large or small? I have all sizes of clamps and I use the 12 and 18 inch clamps the most and 24” every so often. One of the first things I built was a blanket chest using some old beat up pipe clamps and wedge clamps so I bought some large clamps thinking I would use them for what ever I wanted to build. I gave up trying to use a 48” clamp on a 12 ” box.

As mentioned this depends what you plan on building. The bar clamps I use most is the 24” (even on the smaller panel glue-ups). Only occasionally use 36” or 48”. In the last two years I’ve needed some 72” bar clamps only once.
The only disadvantage to a longer clamp is the excess overhang of clamping bar or pipe if it gets in the way.

The only clamps I have less then 24” are the F-clamps and Quick-Grips. The F-clamps I use most are 6” and 12” vs. the 24” and 36” I have. With the Irwin Quick-Grips I use most are 6” and 12” vs. the 24” and 36” I have.

I really like my Jet 31”, I find the extra weight and capacity are not an issue. If you find them at a good price I would buy the 31”. If you want, they can always be shorten, but cannot be lengthen. My shorter clamps I use are more the F-Style clamps and my Quick Clamps. Dan

Buy whatever you decide, but always check whether you have what you need before applying the glue.

If you’ve got to choose, buy the bigger clamps. 24 to 31 inches isn’t enough to be annoying when you’re using oversized clamps…but they do offer 7 extra inches of clamp.

I agree here. I’ve got these sizes and much longer ones. The 31 inch will come in handy sometime and for smaller sized glueups they will work fine and aren’t that much difference in ‘awkwardness’ compared to the 24’s.
Nothing is more frustrating when you need to clamp something and the clamp needs just another inch more to open up to use it.
