Chairs for placing rebar in tilt-up slabs. Similar to standard caged rebar chairs, but with fine points on each leg to minimize visibility on the finished surface. Each chair holds rebar at the listed height and also at a second height 1.3 cm lower (for example, a 5 cm chair supports covers at 3.8 cm and 5 cm).

Stackable design allows multiple heights—bottom, intermediate, and top layers—so rebar stays properly spaced. Provides good stability and allows concrete to flow freely around the spacers. Reduces or eliminates the need for custom supports, saving time and money.
