10 Pack 1-1/4" x 1-1/4" Tee Joint End Rail Pipe Clamps, 3 Way Connector Chain Link Fence

I use schedule 40 pipe on most projects so had to return these but before sending back, I did notice they seem very sturdy, small but sturdy. My boy didn't have any screws or boots so another reason they had to be returned but if you're using a small diameter tube and don't mind buying your own boots, they may be perfect for you. Maybe bolts are normally included and mine just got left out, IDK.

These brackets do work. However, the through holes for the 6mm bolts. The square hole side would be for a carriage bolt which would be great except that they are for 6mm / metric bolt. Finding a 6mm carriage bolt is like pulling teeth from a duck. Had to drill out all holes to accommodate a 1/4-20. Use hex head 1/4-20. This kit should come with hardware, I would have gladly paid more if it came with appropriate hardware.

I used the product for building my dog pen

Worked well to put emt conduit over a dog run to make support for tarp. I used 3/4” conduit, it holds it tight, but don’t think it would hold 1/2” tight. Does not come with bolts

Nice but the holes are very tight for 1/4 bolts and the square cutout for cottage bolt is too small to allow the bolt to fit down into it for tightening!
