Arlington Industries MM-Series Meter Mounting Base - UV-Rated Non-Metallic, 1" Overhang, Made in USA

Arlington Industries Meter Mounting Base - UV-Rated Non-Metallic, 1" Siding Overhang

The Arlington Industries MM-Series Meter Mounting Base is a UV-rated non-metallic mounting base engineered to create a flat, weathertight surface for electric meter sockets on any siding type. The 1" overhang lip seats flush against the siding profile, eliminating gaps that trap moisture and cause long-term damage to the wall assembly. White finish, domestic manufacture, and three size options make it a go-to for residential new construction, multi-family retrofits, and commercial service upgrades.

Key Features

• UV-Rated Non-Metallic Construction: Resists UV degradation, cracking, and corrosion - built for permanent outdoor exposure.
• 1" Siding Overhang Design: Seats cleanly against the siding face to prevent water infiltration behind the meter socket.
• Universal Siding Compatibility: Works with vinyl, wood, fiber cement, stucco, and other common siding profiles.
• Three Sizes Available: 7"×10" (MM10), 15.875"×17.625" (MM18), and 17.625"×23" (MM23) - select the size that matches your meter socket footprint.
• White Finish: Clean appearance that blends with standard residential and light-commercial exteriors.
• Made in the USA: Arlington Industries domestic production.
