Building Material Slab Bolster Chairs-Concrete Rebar Chairs

Slab Bolster

Slab Bolster is used to support rebar and mesh at the proper elevation in concrete slabs. The legs are spaced 5” on-center and spot-welded to resist bending.

When a runner wire is spot-welded to the feet along the full length it becomes Slab Bolster Upper. This provides support on soft surfaces or upper rebar levels.

Standard heights from 3/4” to 4”, in 1/4” increments, with other fractional sizes available on request. Options include plastic-dipped or plastic-tipped feet, and/or an epoxy-coated or galvanized finish.

High Chairs

Individual High Chairs are used to span and straddle lower rebar, while “cradling” upper level rebar at the proper elevation. The legs are spot-welded to resist bending under rebar load.

Standard heights from 1” to 12”, in 1/2” increments, with other fractional sizes available on request. Options include plastic-dipped or plastic-tipped feet, and/or an epoxy-coated or galvanized finish.
