Description+

High Chairs are designed for strength. Two heights on the same rebar chair mean unrivalled versatility. Our High Chairs are the most robust of the market, being manufactured with a resin specially designed for their application. What's more, the lugs at the base of the High chairs are designed to leave no marks when the formwork is removed. The High chairs are often used in pair with our slab bolster. They serve to support a second or third row of rebars on your top slabs. Their unique shape makes work easier for users, they can easily be place through the Slab Bolster or other chairs reinforcement. This product ensures optimum concrete flow to help prevent voids or linear cracks in concrete.

The High chairs are available on heights from 3″ to 9″ in 0.5" increments.
