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.
