Abstract
Abstract A plurality of parallel bridge supporting rails for the lead plates of a storage battery for location in the bottom of the battery box, which rails are connected together by parallel cross bridging members of lesser height than the rails, whereby mud from the battery plates is free to settle and move under both the rails and the cross bridging members. The rails and cross bridging members are molded as a unit from a reinforced, plastic material which has smooth and rounded upper surface to which mud does not adhere.
