Teenyyou Marine Cup Holders for Boat Rails 4 Pack, Classic, 360° Rotating ABS Clamp, Fits 14–50 mm

Made for boating, fishing, and waterside leisure, this set of four Teenyyou cup holders is a no-drill solution that mounts to round or angled rails from 14 mm to 50 mm. Each holder rotates 360° and uses a flexible ABS body with an adjustable knob and anti-skid pads so you can position drinks for convenience and stability on deck, docks, kayaks, or pontoon rails.

How do these cup holders attach to my boat rail?

The Teenyyou holders use a clamp-style mount that tightens with an adjustable knob—no tools or drilling required. Pads included increase friction and protect rail finishes while keeping the clamp from sliding under motion.

• Fits rails 0.55" (14 mm) to 1.97" (50 mm) in diameter
• 360° rotating clamp lets you angle the cup holder horizontally or vertically
• Anti-skid pads protect the surface and add grip
• Tool-free installation in minutes

What sizes and container types will the holder accept?

Each Teenyyou holder has a 3.7" internal diameter and 4.33" height, accommodating most standard cups, travel mugs, water bottles and canned beverages. The flexible ABS material allows for a snug hold on various shapes.

• 3.7" (≈94 mm) opening suitable for cups to large bottles
• 4.33" (≈110 mm) depth for taller containers and insulated mugs
• Flexible rim reduces rattling and holds irregular containers
• Secure grip prevents spill-prone tipping during movement

Will these survive marine conditions and rough water?

The holders are molded from durable ABS plastic and designed for everyday marine use. While not metal, ABS resists impact and bending; the clamp plus anti-slip pads reduce movement so drinks stay put during normal boating activity.

• Durable ABS construction resists bumps and flexing
• Adjustable clamp minimizes slippage on wet rails
• Easy to remove and store when not in use to prolong life
• Not susceptible to rust like metal mounts

How will these cup holders improve my boating setup?

They free up flat surfaces and drink trays by giving each passenger a stable place for beverages that stays with the rail. The rotating clamp adds versatility so you can mount at convenient angles, and a set of four covers multiple passengers or positions around the boat.

• Creates dedicated drink stations without altering the boat
• Rotating mount adapts to different rail orientations and seating
• Simple removal for cleaning or storage between trips
• Set of four supplies multiple seating zones or spare replacements

Who is this for? The Teenyyou 4-piece marine cup holder set is aimed at boat owners, kayakers, anglers, and anyone who wants a practical, no-drill drink solution for rails and poles. It’s especially handy for people who rent boats or prefer not to modify their vessel, renters who need quick installation, families seeking safer drink storage, and as a compact gift for boating enthusiasts.
