CageCaster® Rebar Cage Spacers
The CageCaster® rebar casing spacer is a heavy-duty steel frame with a solid HDPE wheel used to centralize heavy reinforcing steel cages within drilled shafts, rock sockets, and battered drilled shafts—including spiral reinforcing steel cages. CageCaster® spacers provide the support needed during cage installation and help keep the rebar cage centered throughout concrete placement.
*Zinc Coated Available

CageCaster® rebar cage spacers properly position reinforcement cages every time.
The CageCaster® heavy-duty rebar centralizer installs with the same tie wire used to assemble the reinforcing steel cage. Built for drilled shaft construction, these spacers provide quality assurance for drillers, contractors, engineers, and inspectors by helping ensure the reinforcement cage is consistently centered and held off the shaft surface during placement.
