The Hobie H-Rail Ram Ball attachment allows you to attach Ram Ball mounted accessories to the Hobie H-Rail. The Ram ball clamps to the 12-sided H-Rail without any drilling or tools needed. When the clamp is secured, the Ram ball 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 Pro Angler 12, 14, and 17 kayaks.
Perfect mount for my Humminbird Helix 7 with RAM Medium 1.5# stem and the rear H-Rail for the Yak Attack Flag.
Pros: Awesome; the fact that the ball can be easily moved and very secure. Cons: The clap needs to be adjusted to ensure proper fit or you will bend the rail. The pin that holds the ball and clap will shake itself free; I noticed this after a long ride and one of my pin had almost fallin' out. I secure all pins on my kayak with gorilla glue.
