★★★★★
This bracket is HEAVY! Welds and quality are impressive. Very happy with this bracket!
★★★★★
The welds are professional... no sharp edges or points. I'd like to see more products from SolarPanelPoleMount.com.
★★★★★
The components are thick zinc coated steel, very heavy duty and will definitely not bend or break. All hardware was included. It just bolts to the top of a pipe, very easy.
