Abstract
Abstract An improved system for supporting a plurality of conduits above another in parallel, spaced-apart relationship including a base unit for supporting the bottom conduit, the base unit comprising a base and a generally U-shaped member having an open end for receiving the bottom conduit and supporting same, and an intermediate unit including first and second U-shaped members, the open ends of which extend in opposite directions whereby an intermediate unit can be pushed down onto one conduit and positioned to support another conduit thereabove. Both the base unit and the intermediate unit include means for guiding conduits into the U-shaped members thereof and means for locking conduits therein after being located. The intermediate unit also comes in modular form to permit interconnecting of different sizes of conduits. Each unit includes matching interlocking means attached to opposite sides thereof whereby adjacent units may be interconnected to support multiple columns of conduits with a desired horizontal spacing.
