ABSTRACT:
The bracket described herein comprises a device for supporting and holding the sidewall of a conduit trench. These conduit trenches are designed to lie on the ground or may be submerged with the top at ground level. Pipe, conduit, electrical cables, etc. may be laid in the trench with the sidewalls held in place by this new bracket. The bracket comprises two angle irons spaced parallel to each other and fastened to each other by crosspieces at the ends thereof. The angle irons have slots or grooves at each end thereof into which the flat base of a vertical member may be inserted. The flat piece of this base is inserted into the pair of slots or grooves to the end of the angle irons where the crosspiece will stop the movement of the vertical piece. The crosspiece serves as a base for the retaining wall and the vertical piece of the bracket holds the wall in a vertical position.
