This month's gimmick and gadget is a valve box aligner constructed of 2 1/4‐in. square stock welded to steel tubing, to which four spacers are attached. The aligner is placed over the valve wrench nut prior to installation of the valve box. After the trench has been backfilled, the aligner is removed easily from the box.
