Technical Product Data Sheet


The UnichairTM Plastic Rebar Support (Patent Pending) is an all purpose individual high chair ideal for use on wood, steel, and concrete. It is also well suited for TILT-UP applications. They have been tested and approved for Department of Transportation(D.O.T) use.


  • The OCM UnichairTM Plastic Rebar Support (Patent Pending) has an open center which allows concrete to flow through the center of the chair to improve aggregate flow and concrete consolidation.
  • Made from high strength plastic material, so they perform very well under normal loads and will not rust.
  • They have angled legs to prevent torsion and buckling.
  • Sizes above 4 3/4" have an added ring for improved strength and stability.
  • Feet are tapered so there is minimum surface contact to make chairs virtually disappear when form face is stripped. Legs can also be stapled for added stability.
  • Cradle shaped top to aid in positioning of rebar.
  • Concrete gray color helps them to blend in with concrete color.
  • Dual cradle head allows for 1 chair to be used for 2 different heights. Decreases amount of inventory, and increases flexibility for use of each chair.
