International Dock SPC-36-4A-498 Shore Power Pedestal - 4 Receptacle

The International Dock Products SPC-36-4A-498 is the company's mid-tier 4-receptacle shore power pedestal for marina docks and private slips - the cone-top, 36-inch tall, four-receptacle configuration that handles the typical mid-size marina slip with both 50-amp and 30-amp service combined into one pedestal. International Dock Products is one of the major US dock pedestal manufacturers, building marina infrastructure that lasts decades in the harsh dock environment of saltwater spray, UV, and constant cord-plug-unplug abuse. The SPC-36-4A-498 specifically is the 4-amp configuration code 498 - two 50A 125/250V receptacles plus two 30A 125V receptacles, with water and hose holder accessories.

4 receptacles for 4-boat or dual-boat-twin-cord service. The receptacle configuration is sized for either four separate boats (each plugged into one receptacle - typical scenario for a 4-slip dock arm where one pedestal serves multiple slips) or two boats with twin-cord 50A service requirements (each boat using one 50A and one 30A receptacle for the boat's complete shore power needs). For typical marina layouts with 4-slip dock arms, this pedestal serves the whole arm from one location.

Two 50A 125/250V upper receptacles. The 50-amp receptacles deliver the full 125/250V dual-voltage shore power that bigger boats (40+ foot sailboats and powerboats with full shore power systems) require. 50A 125/250V is the standard for serious marina shore power and gives the boat the full electrical capability for AC compressor cooling, water heating, multiple AC outlets, and battery charging without overloading the shore connection. Mounted upper position for easier cord routing on bigger boats with high freeboard.

Two 30A 125V lower receptacles. The 30-amp receptacles are the standard for typical mid-size recreational boats (25-40 foot range) that don't have the full 50A service requirements. 30A 125V handles typical onboard battery charging, refrigeration, basic AC outlets, and lighting - everything a typical recreational boat needs at the dock. Mounted lower position for easier cord routing on smaller boats with lower freeboard.

All receptacles mounted at 45-degree angle. Why this matters: 45-degree receptacle mounting (vs straight-out horizontal mounting) lets the shore cord drape naturally downward and toward the boat without sharp 90-degree bends at the receptacle. The natural cord drape reduces stress on the shore cord at the connector, which extends cord life dramatically. Sharp cord bends at the connector are a leading cause of shore cord damage and the eventual electrical issues that follow. The 45-degree mounting eliminates that failure mode.

Aluminum powder-coated receptacle covers. Each receptacle has a hinged cover (closes when the receptacle is unused) made from aluminum with the same powder-coated finish as the pedestal body. Aluminum doesn't corrode in saltwater the way galvanized or zinc-plated steel covers do, and the powder-coat finish protects the aluminum from oxidation and UV. For a part that's repeatedly opened and closed in the marina environment, the marine-grade material choice matters for long-term function.

Cone top design. The cone-shaped top sheds rainwater away from the pedestal interior - water that pools on flat-top pedestals eventually finds its way inside through cover gaskets and cable penetrations, and then lives on the electrical components causing corrosion and eventual failure. The cone top is a small detail that meaningfully extends the pedestal's electrical reliability over years of weather exposure.

White powder-coated finish inside and outside. Powder-coating provides a tough, UV-stable, corrosion-resistant finish that handles the marina environment dramatically better than spray paint or basic enamel finishes. The white color reflects sunlight (lower internal pedestal temperatures during summer days, which protects the internal electrical components from heat-induced degradation) and stays visible in low-light dock conditions for safety. Inside-and-outside coating means the interior is also protected from corrosion - critical because moisture inevitably finds its way inside any electrical enclosure over years.

All 316 stainless fasteners with nylon washers. The hardware is 316 stainless steel - the highest corrosion-resistance grade in economical stainless steels, ideal for direct saltwater exposure. Nylon washers under each fastener prevent galvanic corrosion between the stainless fastener and the aluminum / steel pedestal body, AND prevent the fastener from working loose due to vibration. Cheaper pedestals use 304 stainless or zinc-plated fasteners that visibly deteriorate within a few seasons of saltwater exposure.

Two standard water spigots. The pedestal includes two standard threaded water spigots (one on each side) for hose connection - meaning you can connect dock water service to the boat for boat washdowns and onboard fresh water tanks. The two-spigot configuration matches the four-receptacle setup, giving each potential boat connection point both power and water access. Water inlet on the pedestal connects to the dock's main water supply line during install.

Two non-cast hose holders. Hose holders are simple non-cast hooks (vs the more decorative cast-style holders on premium pedestals) for hanging the dock water hose when not in use. The non-cast design is more durable than cast-aluminum hooks (which crack under impact) and meaningfully cheaper. For functional dock infrastructure where appearance is secondary to function, non-cast hooks are the right choice.

PL-7 fluorescent light with photocell. The integrated dock light uses a PL-7 fluorescent lamp (compact 7-watt fluorescent that's the standard dock pedestal lamp size) with an integrated photocell that automatically turns the light on at dusk and off at dawn. Critical for safety on darkened docks - boats coming in late, owners walking dock at night, slip approach in low visibility. The photocell eliminates the need for manual switching and makes sure the light is always on when needed.

Round and flat mounting brackets included. The kit ships with both round and flat mounting brackets - round for mounting to round dock pilings (pile-mount installations), flat for mounting to flat dock surfaces (deck-mount installations). Most pedestals from competitors ship one bracket type and require ordering the other separately. International Dock includes both, which simplifies install whether the dock geometry is round-pile or flat-deck.

Direct-feed power distribution box. The internal power distribution box accepts the marina's main power feed directly - no separate junction box needed. Maximum wire size accommodated is 2/0 AWG (large enough for 50A 240V service entry with appropriate margin). The internal distribution lugs and breakers are pre-installed and labeled.

Compact 6 x 6 inch base, 36 inches tall. The 6 x 6 inch base footprint fits typical dock plank or piling mounting locations without taking up significant deck space. 36-inch overall height puts the receptacles at reasonable hand-height for standing access while keeping the pedestal compact enough to not become a navigation hazard on the dock. The compact footprint matters on tight dock layouts where every square inch of dock surface is valuable.

15-year unconditional warranty on structural casing. International Dock backs the SPC series with a 15-year unconditional warranty on the structural integrity of the casing - meaning if the pedestal body fails (cracks, corrodes through, or otherwise loses structural integrity) within 15 years under normal use, they replace it. The 15-year term is meaningfully longer than the typical 1-5 year warranty on competing dock pedestals and reflects the company's confidence in the corrosion-resistant construction. Note: the warranty is on structural integrity specifically. the electrical components (receptacles, breakers, light, photocell) are covered under separate warranty terms typical for marina electrical hardware.

Install. Dock pedestal install is involved - typically done by marina electricians during initial dock construction or major refit. Plan: select round or flat bracket based on mounting surface. Mount the bracket to the dock piling or deck. Run the marina's power feed (up to 2/0 AWG) and water supply lines through the dock penetration to the pedestal location. Connect the power feed to the internal distribution box (proper marina-grade installation per NEC and local codes). Connect the water supply to the pedestal's water inlet. Connect the lighting circuit if separate from the main power feed. Mount the pedestal on the bracket and secure with the supplied 316 stainless fasteners. Total install time varies dramatically depending on the dock-side electrical and water infrastructure. for a properly-prepared dock site, install runs 4-8 hours per pedestal.
