Hoffen Stainless Steel Cup Holder Inserts for Marine RV Camper — 4‑Pack with Drain, Gaskets & Anti‑Slip Strips

Hoffen cup holder inserts are stainless-steel, drain-equipped liners designed to protect, secure and drain drinkware in marine, RV and camper environments.

These removable inserts convert standard round cutouts into durable, rust-resistant holders that keep beverages upright, collect spills and allow water to escape. Built from high-grade stainless steel with a mirror-polished lip and brushed body, the set includes gaskets and anti-slip adhesive strips so installation is simple and the fit stays snug under motion or vibration.

How do these cup holders improve safety and convenience on boats and RVs?

By lining existing cup cutouts with a rigid stainless-steel sleeve, these inserts reduce tipping and contain condensation or small spills. The integrated drain lets liquids escape instead of pooling, helping avoid slippery surfaces and odors.

• Securely holds cups, cans and small bottles to minimize tipping.
• Drain feature channels spilled liquid away from the holder base.
• Anti-slip tape prevents rotation and movement during travel.
• Stainless construction resists corrosion in wet environments.

What are the dimensions and will they fit my existing cutouts?

Each insert measures approximately 3.8 inches high with a 3.5-inch inside diameter and a 4.25-inch outer diameter including the flange. These dimensions suit many standard marine and RV cup cutouts, but checking your countertop or console opening ensures the best fit.

• 3.8" height fits common consoles and counters.
• 3.5" internal diameter fits most cans, cups and travel mugs.
• 4.25" outer diameter with flange covers rough cutout edges.
• Gasket and adhesive strips help adapt to slightly irregular openings.

How are these inserts installed and maintained?

Installation is straightforward: seat the gasket, press the stainless insert into the cutout and use the supplied anti-slip adhesive strips for extra hold. For maintenance, wipe clean or remove the insert to rinse; stainless steel resists staining and rust so upkeep is minimal.

• Includes gasket to create a tight, water-resistant seal.
• Adhesive tape strips hold the insert in place under vibration.
• Removable for easy cleaning or replacement.
• Mirror-polished lip wipes clean quickly; brushed body hides minor scratches.
