Benefits

  • Mix and match holders and devices. Reuse prior investment in other vendor's bases and device holders that may have a 20mm or 25.4mm (1") diameter ball.

  • Add an clamp set to the end of a 67 Designs' arm "core" and you can then attach a complete arm to a holder or base from another manufacturer.

  • Cast metal for years of service.

Available Packs

The options to connect a 67 Designs carbon fiber series "core" to 20mm and 25.4mm (1") ball hardware are as follows:

  • 1 x 20mm clamp.
  • 2 x 20mm clamp sets.
  • 1 x 20mm arm clamp and 1 x 25.4mm (1") arm clamp.

CAUTION: Not designed to work with any other manufacturer arms. Only works with 67 Designs "cores". Using with non-67 Designs arms voids the warranty.
