Sea-Dog 2" Gauge Power Socket Adapter Mounting Plate

The Sea-Dog 2" Gauge Power Socket Adapter Mounting Plate is an essential instrument panel adapter for marine and automotive applications where dash-mounted gauges and meters are required. This mounting plate solves a common installation challenge: fitting standard 1-1/8-inch gauges into oversized 2-inch instrument holes found in modern dashboard designs. Whether you're upgrading your engine bay instrumentation, replacing worn gauge clusters, or integrating aftermarket pressure, temperature, or electrical monitoring systems, this adapter provides a professional, seamless solution that maintains dashboard aesthetics while ensuring secure gauge installation.

Engineered by Sea-Dog, a trusted manufacturer of marine and automotive hardware, this mounting plate works by positioning a faceplate in front of the dashboard hole, allowing you to mount 1-1/8-inch gauges where the dash opening is 2 inches. The adapter effectively bridges the size difference, providing a flush, professional appearance without visible gaps or loose fitment. The robust construction ensures that vibration and engine movement won't compromise gauge position or accuracy. This is particularly valuable in modified vehicles where custom gauge clusters are common—whether you're monitoring fuel pressure, oil temperature, boost levels, or transmission temperature in a tuned engine build, reliable gauge mounting is non-negotiable for both safety and performance diagnostics.

This adapter is ideal for mechanics, fabricators, and vehicle enthusiasts performing dash modifications, engine bay upgrades, or gauge cluster replacements on trucks, cars, boats, and industrial equipment. If your project involves a 2-inch dashboard hole and you need to install standard aftermarket gauges, this Sea-Dog mounting plate ensures compatibility without costly custom fabrication. Its lightweight design (1 lb) makes installation straightforward, and the professional finish integrates seamlessly with most automotive and marine interiors. Confirm your dashboard hole diameter before purchase to ensure proper fit with this adapter.
