No welding needed

Perfect for DIY enthusiasts who do not have welding equipment. The instructions were clear and all hardware was included.

Great for shelving

Used these for my garage storage racks. Very sturdy and the galvanized finish looks professional. No welding made the project much faster.

Good but tight fit

Quality is excellent but the fit on the 25mm tube was slightly tight. Needed a rubber mallet to slide them on properly.

Exact fit for 25mm

Measured my tubes carefully before ordering. The 25mm connectors fit perfectly with no wobble. Highly recommend for framing.

Sturdy connection

Holds weight well without bending. I was worried about the bolted connection but it is very tight and secure once assembled.
