Determine your optimal pole clamp choice

Armrest width dimension is measured from the outside-to-outside of the armrests. Lateral riser stack centres are measured bolt centre to bolt centre of the riser stack.

How to Use This Calculator

Select your mounting type, enter your armrest width measured outside-to-outside, then enter your lateral riser stack centres. The calculator realigns the centres and recommends the pole clamp option that keeps your armrests optimally aligned with your extension poles.
