Universal AC holder for ProMariner chargers

The Promariner 51300Plug universal AC holder converts a standard plug holder into a watertight AC inlet for compatible ProMariner engineered chargers. It is finished in black and includes a plug clamp insert plus stainless steel mounting screws. No cutting, stripping or rewiring of the existing AC power cord is required.

Plug clamp insert and stainless hardware

The supplied clamp insert secures the power cord inside the holder, creating a weather-resistant seal that resists UV exposure. Stainless steel mounting screws are provided so the assembly can be fastened directly to the mounting surface without sourcing separate corrosion-resistant fasteners.

Simple surface mounting

Installation consists of positioning the holder, driving the included stainless screws and snapping the clamp insert over the cord. The only common issue is misaligning the screw holes on uneven surfaces, which can prevent the watertight seal from seating correctly.

Questions about this item

Does the stainless-steel mounting hardware supplied with the 51300Plug ever need replacement?

The holder ships with stainless-steel mounting screws; in typical marine use they resist corrosion for years, but inspect them annually and replace any that show pitting or thread wear.

What is the first limitation you hit when the holder carries a live AC cord continuously?

The watertight, UV-resistant seal around the clamp insert is the primary barrier; prolonged UV exposure and repeated cord insertion can degrade the gasket before the plastic body shows fatigue.

How much heat does the universal AC holder generate during all-day operation?

The holder is a passive mechanical inlet with no electronics, so it produces no measurable heat; only the charger and cord behind it will warm up under load.
