Core Features
This drink holder is designed for secure and convenient rail-mounting without drilling or tools. The adjustable clamp firmly attaches to the rail, while the 360-degree rotating knob helps keep the holder stable at various angles.

Suitable Scenarios
Suitable for use on yachts, pontoon boats, bass boats, Jon boats, kayaks, and personal watercraft. It can be installed on horizontal, vertical, or angled rails, allowing for flexible placement based on the boat's layout. The movable clamp-on design makes it practical for users who want to relocate the cup holder to different parts of the rail as needed.
