FREQUENTLY ASKED QUESTIONS ABOUT AMERICAN SPACER'S SPACERS FOR THE CONCRETE INDUSTRY
Concrete spacers are little concrete parts which are used to position the rebar on the right place with the right cover. These spacers bars and blocks are important for the optimum adhesion of the poured concrete.

A rebar spacer is a device that secures the reinforcing steel or “rebar” in reinforced concrete structures as the rebar is assembled in place prior to the final concrete pour. The spacers are left in place for the pour to keep the reinforcing in place, and become a permanent part of the structure.
