This all-aluminum arm converts between Tackform's 20mm Enduro system and 1"/25mm/B-sized ball mounts or cradles. It is the shorter modular option for adapting existing 1" parts to a 20mm base.
It measures 4.75" end to end and has an expandable elbow joint. A separate arm extension adds 3.75" of length, sold separately.
Why it works
- 20mm socket on one end, 1"/25mm/B-sized socket on the other
- All-aluminum construction
- Expandable elbow joint
- Optional 3.75" extension if you need more reach later
Fitment
Universal. It has a 20mm socket on one end and a 1"/25mm/B-sized socket on the other.
Related lengths
The 3.75" adapter arm and the 7.25" modular arm do the same 20mm-to-1" conversion at shorter and 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.
