Arm Clamps for 67 Designs Arms

Installation is Easy. Undo the included fasteners and attach to a 67 Designs' carbon fiber arm (not included) and any existing hardware that has a 1 inch ball. Installs in seconds.  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.
