    I ordered these three-way corner couplers and they were perfect for my steel frame outdoor project. Easy to order and definitely was reasonably priced!

    Customer friendly, service was exceptional. Ordered 3 - 4’ sections & 1 - 8’ section for exterior kitchen. Prompt delivery, easy assemble, the couplings fit and afford a tight square setup. I would recommend the connectubes and use them again.
