ABSTRACT:
The mortar cap receives cementitious materials therewithin, such as cement, mortar, and the like, to define a footing for a catch basin grating, and has a base frame with parallel, spaced-apart walls, and an ancillary frame also with parallel, spaced-apart wall. The base frame is set within the ancillary frame, and the latter is slidably and vertically displaceable relative to the base frame. The ancillary frame has a plurality of knobs projecting from wall surfaces thereof which confront given w=all surfaces of the main frame, and the given wall surfaces of the main frame has a plurality of racks of ribs. With vertical displacement of the ancillary frame, relative to the main frame, the knobs engage the ribs and, as a consequence, the ancillary frame is arrestingly held in the displacement.
