Hairpin™ Wheel Spacer Extender

 

Hairpin™ ShaftSpacer Extender Logo

The Hairpin™ rebar spacer extender works with the ShaftSpacer® wheel to achieve eccentric spacing requirements or meet seismic design considerations. Designed for drilled shaft construction, the Hairpin™ extender allows you to meet unusual clearance specifications without requiring oversized wheels.

When Should You Use the Hairpin™ Wheel Spacer Extender?

Unusual Design Clearance

Example: The project specification requires 9-inch clearance. Achieving this with a wheel alone would mean using an 18-inch diameter wheel. By adding the Hairpin™ extender to a standard ShaftSpacer® wheel, the required clearance can be achieved without oversizing.

Close Spacing of Horizontal Rebar

Example: The project specification requires 6-inch clearance, but the spiral pitch is only 4–5 inches. In this case, the ShaftSpacer® wheel sized for 6-inch clearance is too large and interferes with adjacent spiral bars. The Hairpin™ extender solves the problem by providing the clearance needed without bar interference.

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.
