Perfect fit
Exactly what I needed for 40mm tubes. The 3-way and 4-way options allowed me to build a complex frame easily.

Good value
Fit well but were a bit tight initially. Once tightened, they hold the structure securely. Good value for the price.

Durable coating
Galvanization looks thick and should prevent rust. Only giving 4 stars because shipping took a bit longer than expected.

No welding needed
Saved me a lot of time not having to weld. The bolts are strong and the galvanization looks durable. Highly recommend for DIY shelving.

Sturdy and reliable
Used these for a warehouse rack project. They fit the 40mm tubes perfectly and feel very solid. No welding needed which saved me a lot of time.
