The YakAttack Mighty Mount for Hobie H-Rail allows you to easily attach your VisiCarbon Pro to your Hobie H-Rail. It clamps to the 12-sided H-Rail without any drilling or tools needed. When the clamp is secured, the mount does not twist or slide along the rail. Loosening the clamp allows you to remove the accessory or slide it along the length of the rail. Fits the H-Rail on all 2015 and later Pro Angler 12, 14, and 17 kayaks.
