ABSTRACT:
A valve or curb service box having different sized pairs of opposed openings shaped to conform to the cross section of a valve body thereby securing the valve against substantial rotation from a desired vertical orientation, each opening being provided with a detachable cover which may be removed from any pair of opposed openings to accommodate a valve of complimentary shape and dimension and which when unremoved on adjacent openings provides bearing surfaces for back-fill thereby providing both structural strength for the valve housing against distortion and a barrier against intrusion of fill around the valve housed therewithin.
