ShaftSpacer®


Plastic Shaft Spacer for rebar

ShaftSpacer®

A guide and alignment system for bar reinforcement positioning within caissons, drilled shafts, and other geotechnical construction applications.Positioning rebar within appropriate clearances is critical, making spacing and support devices essential for inspection standards. Our line of rebar cage centralizers provide the appropriate space requirements in order to maintain that rebar is in the correct position during the construction process and throughout concrete placement.

Shaftspacers® Insure that bar reinforcement is properly spaced and aligned within the confines of the drilled shaft or excavation. These durable plastic spacer wheels provide quality assurance for the contractor, engineer, and inspector. Installation is quick and easy requiring only unskilled labor.


SHAFTSPACER® is currently available in four models

Offset Hairpins are available in tandem with the SS series to comply with eccentric spacing requirements and/or seismic design considerations

different sizes of hairpin bars. The difference is the short (offset) leg. A sketch is attached that shows how the product is used.
