ABSTRACT:
The mortar cap receives cementitious materials therewithin, such as cement, mortar, and the like, to define a footing for a manhole frame, and has a base frame with a pair of concentric, spaced-apart walls, and an ancillary frame, also with a pair of concentric, spaced-apart walls. 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 walls thereof which confront given walls of the base frame, and the given walls of the base frame has a plurality of racks of ribs which confront the knobs. With vertical displacement of the ancillary frame, or a sector of the ancillary frame, the latter is arrestingly held in the displacement due to an interference of the knobs and ribs, and an engagement of the knobs with a pair of the ribs.
