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 service. This is a SAFE installation.
Easily adjusts to grade level. No need to dig when grade changes. Just step-on to push down or pry it up.

A full throat/unobstructed upper tube, allows more room to operate the key.
