This rebar support chair is made entirely out of mortar, it is the spacer of choice when building foundation slabs or floors. We offer this positioner in heights ranging from 17mm to 75mm.
It has excellent load carrying capacity (over 5000psi) and it allows for correct positioning of steel from thin mesh up to one inch thick Steel bars. It can take any kind of traffic over the rebar structure prior to pouring.
With our mortar chair the savings obtained in contrast to other types of spacer are huge, you'll only need 1 to 1.5 units per square meter.
