Adding a drink holder to a boat cockpit, cabin or RV dinette? First choose where and how it will mount. A recessed holder needs a correctly sized hole and open space beneath the deck or counter. A folding holder fixes onto a flat face. Sea-Dog also makes a removable, swivelling wire holder for a wall or bulkhead. These five options differ in ways that matter before you cut or drill.

Three ways to mount a marine drink holder

Drop-in recessed holdersBlack 588060 and stainless 588065 sit mostly below the surface, but they require different openings: 3¾ inches for 588060 and 3⅝ inches for 588065. They are not automatic drop-in replacements for each other.
Folding holders for vertical surfaces588220-1 (black) and 588221-1 (white) fold to just 1 inch when closed. Each adjusts for drink containers as large as 3⅞ inches in diameter and uses four #6 flat-head fasteners.
Removable swivel holder588130-3 is a chrome-plated brass-wire holder with a foam insulator. Its quick-release setup comes with two wall brackets, so the same holder can be moved between mounting positions.

Sea-Dog drink holder size and mounting chart

Exact MPN Holder design Mounting requirement Key distinction
588060 Recessed black 3¾-inch round opening Black high-impact polystyrene; includes drain holes
588065 Recessed stainless 3⅝-inch round opening Stamped 304 stainless; ¼-inch drain tubing required separately
588130-3 Swivelling wall mount Wall brackets; no round cutout Two brackets, quick-release holder, foam insulator and fasteners
588220-1 Folding black Four #6 flat-head screws (not included) Closes to 1 inch; holds containers up to 3⅞ inches across
588221-1 Folding white Four #6 flat-head screws (not included) Same folding geometry as 588220-1, in white

The two circular dimensions above are the manufacturer's specified hole diameters, not the outer flange diameter. For an existing installation, measure the actual cutout and allow for the holder's outside rim, depth and surrounding hardware before ordering.

Five checks before you install

  1. Measure any existing hole. The 588060 calls for a 3¾-inch opening; the 588065 calls for 3⅝ inches. A difference of ⅛ inch can affect how the replacement seats.
  2. Check what lies below the mounting surface. Recessed bodies extend below the flange. Leave enough space for the cup body and any drain hose, and check for wiring, insulation or reinforcement.
  3. Plan drainage. The black 588060 has drain holes. The stainless 588065 has a drain fitting that accepts ¼-inch tubing (not included), a padded rubber bottom and a mounting gasket. Route water safely for the installation.
  4. Confirm screw attachment for folding holders. Both folding models require four #6 flat-head fasteners, sold separately. Check the backing material and the footprint of the holder when folded and opened.
  5. Look for a useful bulkhead position. 588130-3 includes two brackets and mounting fasteners; the 3½-inch and 3¾-inch dimensions on Sea-Dog's drawing describe the swivel holder, not a circular hole to drill.
For a replacement, match the mounting footprint as well as the product style. Similar-looking holders can require different hole sizes, screw positions, clearances or drain routes. Do not enlarge an opening until the installation drawing and available support material have been checked.
