Designed to prolong asphalt life by reducing cracking and reduce snow plow damage, the SELFLEVEL valve box top is supported by and moves with the surrounding road surface. This allows it to remain flush with the road surface.
Lasting longer than traditional valve box risers in situations where there can be frost heave and natural road settling, this “floating” affect also helps prevent road damage and protects by dispersing traffic vibrations and shock throughout the road surface.
The valve box top stays level with the road surface, even when the road heaves due to extreme temperature changes or settling of the pavement. Pavement around the valve box stays smooth for years to come.
The SELFLEVEL valve box top is used with drop lid, bottom, and base to provide the complete solution for valve box access.
