CageCaster® Rebar Cage Spacers

CageCaster Drilled Shaft Rebar Centralizer LogoThe CageCaster® rebar casing spacer is a heavy-duty steel and solid HDPE spacer used to centralize heavy reinforcing steel cages within drilled shafts, rock sockets and battered drilled shafts as well as on spiral reinforcing steel cages. CageCaster® steel frame reinforcement spacers provide the support necessary while the solid HDPE wheel aides in the process of centralizing the rebar cages during installation into the drilled shaft and throughout concrete placement.

CageCaster® rebar cage spacers properly position reinforcement cages every time.

The CageCaster® heavy-duty rebar centralizer is installed with the same tie wire used to assemble the reinforcing steel cage. These heavy-duty cage centralizers are built for drilled shaft construction and provide quality assurance for the driller, contractor, engineer and inspector that reinforcement cages are properly positioned off the base of the shaft every time.
