Product Parameters:
Set of 4 retractable drink holders made of stainless steel in a silver finish. Each holder features a polished, rust-resistant exterior, a wide mounting flange, and an internal diameter of approximately 3.66 inches. The structure includes a built-in drain hole with a drain tube and a non-slip pad at the base for added stability.

Core Features:
These cup holders are designed for marine use and help manage moisture through an integrated drainage system that directs trapped water away from the holder. The bottom plate helps reduce slipping and vibrations, which can limit movement and noise from cans or cups during travel. The stainless steel construction and polished finish support reliable use in demanding outdoor and marine environments.

Suitable Scenarios:
Suitable for boats, yachts, pontoon boats, and RVs. The retractable design also fits a range of installation areas such as seating sections, center consoles, armrests, and table surfaces where a recessed drink holder is needed.

Product Summary:
This 4-piece stainless steel cup holder set combines a clean silver appearance, retractable installation, drainage details, and a base plate design for practical use on marine vessels and recreational vehicles.
