RimRiser
At National Precast we are authorized dealers of the RimRiser manhole adjustment system. RimRiser is the first of its kind, which allows for east adjustment to castings, and Precast tops/Utility vault lids. With RimRiser, adjusting to grade can be done much faster, by one person, and safer; all of this saves you money. RimRiser is a safe and easy system that anyone can use, and the project owners will be impressed with how nice everything will turn out.
