ABSTRACT:
A device for use as a meter pit or a traffic barrel, having double-walled construction in which one wall is a substantially smooth inner wall and a second outer wall is a corrugated wall, wherein the corrugated wall may be a singular wall extending from one end of the inner wall to the other end of the inner wall or a plurality of exterior walls attached sequentially at various points to the inner wall, the exterior corrugated walls may be linked to one another by a series of smooth walls. The corrugated wall has small, individual corrugations with the individual corrugations including a pair of trough walls and a crest, the small size of the individual corrugations making the device light-weight and impact resistant. The drum device is extruded and contains a polyolefin mixture, which preferably contains recycled and virgin polyethylene materials.
