JOYTUTUS Large Cup Holder Inserts 4-Pack — Chrome Drop-In Adapters for 3.74–4.10" Openings

These JoyTutus cup holder inserts are universal drop-in adapters that convert oversized bottles and cups into a secure fit for 3.74"–4.10" base openings.

Upgrade cup storage across your boat, RV, car, couch, golf cart or pontoon table with a simple, durable solution. The JoyTutus set includes four large plastic chrome-finish inserts designed to accept wide-mouth flasks, tumblers and standard drinkware while sliding into existing circular openings. They’re an easy replacement for worn factory holders or a quick way to add cup support where none exists.

Will these cup holders fit my Hydro Flask or Yeti tumbler?

Yes — the JoyTutus inserts accommodate many popular oversized bottles and tumblers as long as the bottle’s base fits the adapter dimensions. Measure the diameter at the bottom of your bottle to confirm compatibility before purchase.

• Fits bases with a diameter between 3.74" and 4.10"
• Recommended maximum cup diameter: up to 3.55" at the insertion point
• Compatible with many Hydro Flask, Yeti Rambler and large insulated bottles
• Works as a replacement for built-in couch or furniture cup pockets

How easy is installation and removal?

Installation is drop-in and requires no tools: just press the insert into a compatible circular opening until it seats. Removal is equally simple when you want to clean, replace or reposition the holder.

• Tool-free drop-in installation for most standard cup openings
• Lightweight plastic construction simplifies lifting and cleaning
• Chrome finish offers a clean, finished look without trim modifications

Where can I use these cup holder inserts around my vehicle or home?

These inserts are designed for flexible use in boats, RVs, cars, couches, golf carts, pontoon tables and other furniture with round openings. The four-piece pack lets you outfit multiple locations at once or replace several worn holders in one purchase.

• Fits pontoon and boat cup recesses, plus RV and camper counters
• Ideal for dashboard, armrest, table, and backseat mounting points
• Also useful for sofas, chairs, and custom furniture cup holes

What materials and care should I expect?

The inserts are made from durable plastic with an elegant chrome-tone finish that resists corrosion in marine or recreational settings. Routine cleaning with mild soap and water keeps them looking new; avoid abrasive cleaners that can dull the finish.

• Durable molded plastic body with chrome-colored surface
• Wipe clean with a soft cloth and mild detergent
• Store indoors or under cover when not in use for longer life

Who is this for: The JoyTutus Cup Holder Insert 4-pack is for boaters, RV owners, drivers, and homeowners who need a reliable way to secure large drinkware in existing cup openings. If you own oversized insulated bottles, have worn or missing cup holders in furniture, or want a quick upgrade to your vehicle or pontoon table, this set is a practical, easy-to-install option.
