Great Quality

These angle braces were really heavy duty - much more-so than I expected. Also, the braces arrived very quickly. Great service

4x4 mount brackets very well made and finished
I would highly recommend this product.
The one suggestion I have to make them superior change the screws from Phillips to torx

Candy W.

Quick shipping ! Good product!

Dave L.

This kit is perfect for building a pergola type structure. All the joints are tight and straight. On shipment the box containing the rafter supports broke open in the ups truck and scattered all over the truck. I had to refuse shipment on that box. Customer service contacted me and had a replacement box shipped with in a day that they were notified of the problem. Recommend both the product as well as their customer service.
