Great for carport assembly

Used these for a custom carport frame. They hold up well in wind and rain. The galvanized finish looks like it will prevent rust for years.

Good product, missing two nuts

The connectors themselves are high quality, but my package was missing two nuts. I had to go to the hardware store to finish the job. Customer service was helpful though.

Simple and effective

Assembled my breeding shed in a weekend. The weld-free design is a game changer for people without specialized tools. Very satisfied with the purchase.

Exactly what I needed for my sunroom

I was worried about stability without welding, but these fasteners are rock solid. The 40mm size fit my tubing perfectly. Highly recommend for DIY enthusiasts.

Sturdy but instructions could be clearer

The metal quality is excellent and feels very durable against the weather. I deducted one star because the diagram on the box was a bit small, but overall a great product.

Perfect for my chicken coop project

These connectors made building the frame incredibly easy. No welding required saved me a lot of time, and the fit on the 30mm tubes was snug and secure.

5 FAQ

Q: Can these connectors be used with round tubes?

A: No, these connectors are specifically designed for square tubes with dimensions of 20, 25, 30, or 40mm. They will not fit round tubing securely.

Q: Are these suitable for outdoor use in rainy climates?

A: Yes, they are made from galvanized steel which provides strong resistance to rust and corrosion, making them ideal for outdoor structures like carports and coops.

Q: Do I need to drill holes in the tubes to use these?

A: In most cases, no. The bolts pass through the pre-drilled holes in the connector and clamp onto the tube. However, for extra security in high-wind areas, drilling through the tube is recommended.

Q: Can I mix different tube sizes in one structure?

A: You can use different sizes in the same structure, but you must purchase the specific connector variant that matches each joint's tube size. A single connector cannot join two different tube sizes together.

Q: What size wrench do I need for installation?

A: Typically, a standard 10mm or 12mm socket or open-end wrench is required for the bolts included in the package, depending on the specific tube size selected.
