• Spa-Stir


Double Cage Reinforcement Spacer

Automatically spaces double cage reinforcement
The Spa-Stir automatically locks two cages into an integral unit of reinforcement and spaces from a single form surface to achieve the proper concrete cover. No welding, cutting, bending, or skilled labor is required. Just snap the Spa-Stir into place and it is securely locked.

Improves pipe quality
When used as a spacer, the Spa-Stir’s stirrup action resists pipe shear and tensile stresses at critical locations and increases pipe strength with no extra material costs. Also, locking two cages into one unit with the Spa-Stir increases pipe stability and reduces fall-out after stripping.

The Spa-Stir is easily used with most manufacturing processes…vibration, packerhead, wet cast, and others. In applications such as wet cast, elliptical cage in round pipe, and elliptical pipe production, the high strength of the Spa-Stir fits any circumferential wire spacing and all wire diameters up to 1/2”. A full range of sizes for both B Wall and C Wall concrete pipe are stocked for immediate shipment. Special sizes are available on request. The versatility of the Spa-Stir is illustrated on the left.

Simple Installation

  • 1. Contacts the jacket and is locked to the circumferential wires of each cage. The 45° twist on the Spa-Stir's hooked end allows the Spa-Stir to be locked to a longitudinal wire illustration
  • 2. Or the intersection of a vertical and circumferential wire illustration
  • 3. For maximum strength. In packerhead applications, the Spa-Stir illustration
  • 4. Positively centers the outer cage in the jacket while the inner cage is locked to the outer cage
