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 7”, 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 fi nish.
Continuous High Chair
Continuous High Chair is used to support rebar and
mesh at the proper elevation in concrete slabs. The
legs are spaced 7-3/4” on-center and spot-welded to
resist bending.
When a runner wire is spot-welded to the feet along the
full length it becomes Continuous High Chair Upper.
This provides support on soft surfaces or upper rebar
levels.
Standard heights from 4” to 10”, 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 fi nish.

elevation in beam form soffi ts. Legs are spaced 2-1/2”
