Irwin Parallel Clamps Review: They Look Great But Perform Terribly

I purchased a pair of Bessey Revo 51″ parallel bar clamps a few months ago, and meant to order a bunch of smaller sizes when they were on sale at Home Depot, but I didn’t. I also own a pair of 24″ clamps, but couldn’t find them.

But, good news – I had brought up a small cache of Irwin parallel clamps that they had sent me a few years ago at my request. I have 6 of the 24″ clamps in my possession, and they ended up in storage until recently.

Great! Just what I need for my weekend project.

I was gluing up 8 drawers that I had cut and sanded last weekend, and they needed some strong clamping, stronger than my Woodpeckers corner box clamps could muster.

I had built these drawers using Festool’s Domino joinery system. With the dominoes being spaced close together, and each being somewhat tight fitting individually, light tapping with a mallet (or scrap piece of 1.5″ x 1.5″ maple stock) wasn’t quite enough to pull everything together. Hence the need for good parallel clamping action.

How do I put this nicely? These Irwin parallel clamps didn’t exactly work out well for me.

Or, as my wife would say, these parallel clamps are so bad, if I saw the designer in the street, I’d want to kick them in the shins.

I’m sorry that I couldn’t run to get some lights and a real camera, as I was more focused on getting the drawer properly glued and set, but you should be able to see how uneven the clamping was.

On some drawers I sawn decent results using the parallel clamp on one side of the box, and then reversing it to tighten up the other side.

But I shouldn’t have to do this. Parallel clamps should deliver parallel pressure.

Doubling up on clamps did the trick, but I shouldn’t have to use 4 clamps to glue up a single 4.75″ tall drawer.

My Bessey Revo clamps were kind of awkward to use, seeing as how they’re 50″ clamps and I only needed 23-something inches of a 24″ clamp’s capacity. But they pulled the joints together perfectly.

Adding insult to injury, some of the Irwin clamps were finicky to use. They wouldn’t open to set up again unless I loosened the handles fully, jiggled things, and even then not all of them would behave as commanded.

On one hand, I was grateful for those Irwin parallel clamp review samples. They pulled me out of a pinch. I was unprepared for the clamping job, thinking my many Irwin box clamps would be enough, when it turned they weren’t. I’m also glad that the Irwin samples were where I could reach them without too much trouble.

On the other hand, I’m frustrated at the lousy quality.

I researched parallel clamps a while back, and Bessey and Jet usually get top recommendations. Between those two companies, I think I’d prefer Bessey Revo clamps, although I believe I once read about Jet clamps doing better in a woodworking magazine’s parallel clamp review. I also won a Bessey Twitter giveaway once, and have a box of Bessey parallel clamp accessories sitting in a box somewhere.

I was hoping that the Irwin clamps would prove to be competitive, comparable, or just plain decent. They’re none of those things. They complicated my project, slowed things down, and while I guess they proved themselves more useful than not, it was a pain having to clamp down on one side and then reverse the clamps, hoping the joint would hold tight throughout, or doubling up to glue each drawer in shifts with 4 clamps in place of 2.

And don’t believe the Amazon product page description where it says these are made in the USA, as they’re not.

I find this to be rough to say, but I would never buy these for use as parallel clamps. They provide strong pressure, but only close to the bar. But lesser bar clamps can provide single-point clamping pressure while costing a lot less. And, as mentioned, the movable jaw can be finicky to adjust back and forth.

I can’t recommend these clamps. I can’t even find a situation where they’d be recommendable. I guess I could recommend them if they were on sale for a fraction of the price of Bessey clamps, but even then they’d have to be a LOT cheaper since you might need 2 Irwin clamps to do the job of 1 Bessey clamp.

Price: $40 (for the 24″ size)

Buy Now(via Amazon)

The Buy Now link is more intended for reference purposes. I would instead encourage you to look at Bessey clamps. Jet clamps also typically receive high recommendations.

I have had great experience with Irwin’s quick grip clamps, with this being my first negative Irwin clamp experience.

Thank you to Irwin for providing the review samples unconditionally.
