ABSTRACT:
A chair for supporting and spacing post-tension cables having a generally tapered body with an upper receiving area for securing the cables and a planar base adapted to rest on a flat support surface. The body has inner and outer surfaces that are substantially complementary to one another to allow a plurality of chairs to be stacked together. The receiving area includes posts extending upwardly between notches. The posts define passageways for guiding the cables into the notches. Detents project inwardly from the tops of the posts and fixedly retain the bars within the passageways. The chair may be formed from a resilient polymeric material.
