IP65 marine protection

Dust-resistant. Water-jet resistant. Built for demanding boat compartments.

The IP65-rated enclosure helps protect against dust, spray, and low-pressure water jets from any direction. It is suitable for many marine battery hatches and center-console installations, but it should not be submerged, pressure-washed, or installed where standing water can collect around the battery.
