Slab On Grade Chair

Plastic supports for rebar and mesh positioning in concrete floors and pavements

The Slab-On-Grade Chair, sometimes called a castle chair or bar chair, supports rebar and mesh at the proper elevation during concrete placement.

The all-plastic, conical chair design will not corrode. Each chair accommodates two forming heights with just a quarter-turn, reducing inventory requirements and allowing for small grade variations.

The integrated base provides stability and support on soft surfaces, without damaging the moisture barrier, insulating foam or other membrane. The holes in the base can be used to fasten or tie chairs in position when necessary.

The Slab-On-Grade Chair meets the requirements to qualify as a CRSI Class 1 Bar Support and meets CRSI requirements per table 3-4.

Plastic chairs support rebar and/or mesh, often in combination with dowel baskets, in concrete floors and pavements.
