This arm measures a touch over 12.25" in total length. It combines extruded aluminum tubing, dual die cast couplers and an elbow joint, for three points of articulation.

It has 20mm sockets at each end, so it fits the Enduro 20 Series ball system and gives you long reach for a device mount, such as a tablet that needs to come well off the dash toward the seat.

Why it works

  • Just over 12.25" of total length
  • Extruded aluminum tubing with dual die cast couplers
  • Elbow joint for three points of articulation
  • 20mm sockets on both ends

Fitment

This is a universal-fit item, not vehicle-specific. What it attaches to depends on the base or mounting surface you pair it with.

It is a 20mm component. It will not mate with 1"/B-size or 26mm parts. For shorter reach, see the 4.5" and 7" dual 20mm arms.

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.
