The slip-type design protects the service from downward pressure. The box absorbs the pressure from above. If all the downward adjustment is used and additional pressure causes the box to collapse further, the bell area will collapse before damaging the pipe. This is a SAFE installation.
Meets DOT requirement 192.181; "If the valve is installed in a buried box, the box must be installed so as to avoid transmitting external loads to the main."
Easily adjusts to grade level. No need to dig when grade changes. Just step-on it to push down or pry it up.
A full throat/unobstructed upper tube, allows more room to operate the key.
Made from SUPERIOR GRADE ABS plastic. It's long lasting and won't rust, rot or corrode.
The box has a 4" upper tube and a 6" bell area.
Fits up to 2" plastic valves. The closed bell gives flexibility for use on many steel valves.
