This is an all-aluminum arm with dual omnidirectional locking ball joints and a locking elbow joint, for finding the right angle on a camera or device. With no plastic parts, vibration stays low.

Why it works

  • All aluminum, no plastic parts
  • Two omnidirectional locking ball joints plus a locking elbow
  • Low vibration, per Tackform
  • 20mm sockets at both ends

Fitment

Universal. It uses 20mm sockets at both ends and belongs to Tackform's 20 Series arms. It pairs with 20mm bases and holders, such as the 20mm camera and tablet holders in the range.

About the length

The title says 4.5" overall, while Tackform measures the length between ball joints at 4". Keep both numbers in mind when you plan where the device will end up.

Other lengths

The 7" and 12.25" dual 20mm arms cover longer reach.

Questions before you order?

Fitment questions are easier to settle before the box ships. Call or text Carl & Anton at (920) 249-7744 or use the chat — real humans in Sheboygan, Wisconsin, not a call center.
