ShaftSpacer® Rebar Wheel

ShaftSpacer® is a plastic spacer wheel guide and alignment system for lateral positioning and centralization of rebar reinforcement cages within caissons, drilled shafts and other geotechnical construction applications. Positioning rebar within specified clearances is critical. Our line of Shaftspacer® rebar spacer wheels ensures appropriate spacing requirements are met and rebar is centralized during the installation of the pile cage and throughout concrete placement.

ShaftSpacer® rebar spacer wheels act as drilled shaft centralizers and properly position reinforcement cages every time, and are a snap to install with minimal cost and installation time. These durable, high-density drilled pile cage spacers are built for drilled shaft construction and provide assurance for the driller, contractor, engineer, and inspector that reinforcement cages are properly positioned every time. We've got your clearance covered.

We have the concrete rebar spacer wheels to match the clearance you need. Don't see the rebar spacer size called out for your project? Take a look at our Hairpin Shaftspacer® Extender. Working on a drilled shaft project? Our Sonitec® crosshole sonic logging (CSL) tubes allow for sonic structural integrity testing of concrete within drilled shafts. The CSL method has been used for more than 30 years and is the most requested method for foundation integrity testing by the Department of Transportation (DOT) and professionals throughout the construction industry.

ShaftSpacer® Minimum Placement Recommendations

Use one ShaftSpacer® per foot (or 304.8mm) of shaft diameter (Minimum of four (4) per tier)

Maximum six (6) foot (or 1.83m) spacing from the top of the shaft

Maximum two (2) foot (or 0.61m) spacing from bottom of the shaft

Maximum eight (8) foot (or 2.44m) interval spacing along the longitudinal axis of the shaft
