WD Valve Boxes is the leader in providing polymer solutions that do a better job for less cost.

After as little as two years in some soil conditions, you may need to replace cast iron service boxes, at a big cost to you. That’s why we produce the only polymer boots available on the market today, perfect for hot soil conditions.

Polymer, with its sound mechanical strength, is stress crack resistant and retains excellent physical properties during weathering. The material actually strengthens after prolonged exposure to the sun’s rays and is at its strongest under frigid conditions. And you can only get it with WD Valve Boxes.
