Scotty 453 Gimbal Adapter w/Gear Head 
Gimbal Mount Adapter
The Scotty Gimbal Mount Adapter has a quick and easy drop and lock system transforming the existing Gimbal Mount on your watercraft into a fully adjustable mounting point for post mounted Scotty rod holders and accessories.
Complete with 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.
Light weight, yet incredibly strong, the 453 Gimbal Mount Adapter is manufactured with engineering grade composite materials.
