Abstract: A tree support block that is easy to install and remove, for temporarily supporting a tree and does not impart damage to the tree. A plurality of one-piece molded support blocks which are designed to be strapped to the trunk of a tree encircling the trunk. A pivotal leg adapter allows for angularly adjustable positioning of each support leg thereby maximizing support configurations. Support stress is transferred from the adapter to the support base such that the entire support force is not borne concentrated at the pivot connection.

Abstract: A shower stall pan that includes an integrally molded threshold “curb” with reinforcing ribs to provide sufficient strength for direct installation into the shower structure. The reinforcing ribs are integrally molded into the shower pan structure, which includes the threshold curb. The use of reinforcing ribs under the curb obviates the requirement to use additional framing under the curb portion of the shower pan, and decreases the time, effort and skill required to install the shower pan and thereby decrease the time and effort in constructing a shower stall.

Abstract: A waterproof shower module comprising a pre-fabricated, integrally molded unit which forms a unitary base having side walls and a pitched floor defining an opening within which is incorporated a vertically adjustable drain. Each side wall includes an upper lip forming a horizontal surface upon which wall board may be supported and flushly aligned with the side walls of the module such that a substantially continuous and uniform surface is formed which provides a suitable mounting surface for receiving shower tiles. The module floor includes a top surface and a bottom surface and defines a plurality of molded feet depending from the bottom surface, which feet function to support the module floor on the underlying subfloor. The module floor is uniformly pitched from each side wall to the drain opening. One of the side walls further defines a curb and includes inner and outer curb surfaces and a horizontal and curb surface. Tile installed on the module's surfaces and on the surrounding wall board.
