Hairpin™ rebar spacer extenders are used in tandem with the ShaftSpacer® wheel in order to achieve eccentric spacing requirements and/or meet seismic design considerations.

When should you consider using the Hairpin™ wheel spacer extender?
Unusual Design Clearance
Example: the project specification and detail states 9 inch clearance. To achieve this clearance with a wheel alone, the wheel would need to have a diameter of approximately 18 inches. By using a Hairpin™ wheel extender in conjunction with one of our standard model ShaftSpacer® wheels, the 9 inch clearance can be achieved.
Close Spacing of Horizontal Rebar
Example: the project specification and detail states 6 inch clearance, but the pitch of the spiral is 4 or 5 inches. Therefore, the ShaftSpacer® wheel that is normally used for 6 inch clearance is too large and will not attach without interfering with the adjacent spiral bars. A Hairpin™ wheel spacer extender is then used to resolve the problem.
