Solid hardware
The bolts included are decent quality. The connectors themselves are heavy duty. Would buy again for future projects.

Saved me so much time
I was dreading welding the frame for my greenhouse. These connectors worked perfectly and saved me hours of work.

Strong and Reliable
Used these for a workbench frame. They hold the weight without any wobble. Great alternative to welding.

Good quality, tight fit
The galvanization looks durable. The fit on the 40mm tube is very tight, which is good for stability but requires some effort to assemble.
