Camco Clamp-On Rail Mounted Cup Holder - Large for Up to 2" Rail - Grey

The Camco Clamp-On Rail Mounted Cup Holder – Large for Up to 2" Rail in Grey provides a secure, dedicated mounting solution for beverage containment on vessels and platforms equipped with tubular rail systems. Designed for 1.5-inch to 2-inch diameter rails, this cup holder uses a tension-adjustable clamp assembly to lock firmly in place without permanent modification to the mounting structure.

The swivel mount design enables installation on rails at any angle, maintaining a level cup holder position regardless of rail geometry or boat pitch. This is particularly valuable on vessels where rail orientation varies across the deck. The clamp tension adjustment screws allow fine-tuning of grip pressure to prevent cup holder migration during acceleration, deceleration, or rough water conditions. UV-resistant construction ensures the grey finish resists fading and material degradation from prolonged saltwater and sunlight exposure—critical for marine environments where corrosion and UV damage compromise standard plastics and coatings.

This cup holder is engineered for operators and crew on offshore fishing vessels, patrol boats, and other watercraft where hands-free beverage storage improves operational focus and reduces spill hazards during dynamic maneuvering. The large format accommodates standard 16–32 oz drinking vessels, coffee mugs, and thermal containers common in extended maritime operations. Field users benefit from the quick-clamp design, which allows repositioning without tools—enabling adjustment as mission requirements or crew preferences shift. At 0.45 lbs, the unit adds negligible weight while delivering substantial utility in confined deck spaces where every inch of unobstructed surface matters.
