## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked great.
*by C***D on March 12, 2025*

I purchased these to attach electrical wiring to an I-beam ... worked great.

### ⭐⭐⭐⭐⭐ As advertised!
*by W***T on August 20, 2023*

Worked great as beam clamps. When purchased, it appeared as the bolts would screw into clamps. But, had to modify with nuts to clamp bolts in place onto beam clamp (one nut on top, one on bottom). Still, good value and sturdy to hold ufo lights on metal C channel/perlin.

### ⭐ Good thing I wasn’t hanging anything with these.
*by S***A on June 1, 2025*

Thankfully I’m only using these to clamp some sheet metal together but I’d be worried if you’re planning to hang things from beams like they are designed. Out of the first 10 I grabbed from the box, two of them the threads gave out before they were tight and one cracked. And before you say I probably over tightened them, I used a 14mm socket on a 1/4 ratchet. For something that’s rated to hold 250lbs that’s pretty bad.
