The Scotty 438 Gear-Head Track Adapter quickly slides into place and locks down your post mounted Scotty rod holders and accessories. Similar to the revolutionary Scotty 428 Gear-Head, this system allows you to quickly change rod holder positions with a simple “twist”. You can use your favorite, fully adjustable Scotty rod holder and adjust it to any vertical or horizontal position without having to drill permanent mounting holes. Designed to fit all kayak track systems and our Scotty Track, this compact product is a must for serious kayak anglers.
