Tired of carrying around heavy concrete grade rings and the pinched fingers and sore back that comes with that? Tired of discarding rings broken in transport? Tired of grouting and then waiting for it to cure before back-filling? Ever wonder if there was a better way to adjust to grade without using shims (or rocks, or branches)?

PRO-RING™ is the only manhole grade adjustment system made from Expanded Polypropylene (EPP). The material is renowned for its ability to stand up to the harshest of conditions without damage or deformity for many years. PRO-RING™ products provide a proven alternative to concrete grade or adjustment rings and is the most advanced concrete-alternative manhole grade adjustment system available anywhere.

Pro Ring System

SAFETY - It usually takes four people to lift a concrete grade ring, each one risking back injury. A 6" PRO-RING™ weights only 6 Kg (14 pounds). Where concrete rings break and can cause injury, the PRO-RING™ system eliminates that hazard, helping reduce comp claims.

EFFICIENCY - One person can easily install the PRO-RING™ system in just minutes. People are always amazed at our demonstration. The rings nest together and include a finishing ring and a slope adjustment ring for a precision fit.

FAST AND COST EFFECTIVE - PRO-RING™ products speed manhole installation and repair dramatically, allowing the site to be closed in one day and reducing overall cost from 20% to 30% based on conditions. No water, sand mortar or bricks are needed, just a few simple tools.
