Arlington Industries MM10 UV-Rated Non-Metallic Meter Mounting Base, 7" x 10", White

The Arlington Industries MM10 meter mounting base is a UV-rated non-metallic mounting platform engineered to create a flat, weathertight surface for electric meter sockets on sided structures. Sized at 7" x 10" with a 1" overhang lip, this base seats flush against vinyl, wood, fiber cement, stucco, and other common siding profiles, closing the gap that lets moisture reach the wall assembly behind the meter socket. Finished in white and manufactured in the USA, the MM10 is part of Arlington Industries' family of meter mounting bases, which also includes larger sizes for bigger meter socket footprints.

Key Features

  • 7" x 10" Footprint: Sized to match standard residential meter socket enclosures, giving installers a precise, ready-to-mount platform.
  • UV-Rated Non-Metallic Construction: Resists UV degradation, cracking, and corrosion for permanent outdoor exposure on any elevation.
  • 1" Siding Overhang Design: The overhang lip seats cleanly against the siding face, preventing water infiltration behind the meter socket and wall sheathing.
  • Universal Siding Compatibility: Works with vinyl, wood, fiber cement, stucco, and other common siding profiles without custom trim work.
  • Part of a Multi-Size Family: The 7" x 10" MM10 is joined by larger 15.875" x 17.625" and 17.625" x 23" Arlington meter mounting bases so installers can match the base to any meter socket footprint.
  • White Finish: A clean, neutral appearance that blends with standard residential and light-commercial exteriors.
  • Made in the USA: Domestic manufacture by Arlington Industries.

Arlington Industries MM18 – Frequently Asked Questions

1) Will the Arlington MM meter mounting base work on vinyl siding, or do I need a different block for lap siding and stucco?
One base covers all of them. The MM-Series meter mounting base is rated for all siding types, including vinyl, wood, fiber cement, and stucco. The 1 inch overhang lip is what makes that work: it laps the siding face instead of trying to sit inside a siding profile, so an uneven lap or a rough stucco surface still closes out weathertight behind the socket. No profile-specific version to pick.
2) Which size Arlington MM base do I need for my meter socket - MM10, MM18 or MM23?
Size off the socket footprint, then go up. The MM10 is 7 x 10 inches, the MM18 is 15.875 x 17.625 inches, and the MM23 is 17.625 x 23 inches. Pick the base that matches or exceeds the footprint of the socket you are mounting. A residential single-position socket usually lands on the MM10; a larger 200A or ringless socket, or one with a factory-installed hub landing, needs the MM18 or MM23 so the socket flange still sits fully on the base and not half on the siding.
3) Can I use a meter mounting base on the sunny side of a house without it yellowing or cracking?
That is the reason for the material spec. The MM-Series base is molded from UV-rated non-metallic plastic, so it is built for permanent outdoor exposure and resists UV degradation, cracking, and corrosion. Being non-metallic, it also will not rust-streak the siding below it the way a painted metal plate eventually does on a west-facing wall.
4) Do I have to buy a case of Arlington MM bases, or can I get one?
Standard packaging on the MM-Series is 10 pieces per pack. For a tract build or a multi-family meter bank that works out fine, but on a single service upgrade you are buying a pack for one wall. Worth knowing before you order for a one-off job.
5) How do you install a meter mounting base so water does not get behind the meter socket?
The base does the flashing work, but only if the lip seats. Mark your fastener locations with the base held in position, then fasten it through the siding into the framing or sheathing so the 1 inch overhang lip pulls flush against the siding face. Check the perimeter for a tight fit before the socket goes on. Then mount the meter socket to the base per the socket manufacturer's instructions and whatever NEC and local code require for the service. Gaps left at the lip are what trap moisture in the wall assembly, so that flush seat is the whole point of the part.
6) What is a meter mounting base actually for - can I not just screw the socket to the siding?
A meter socket bolted straight to lap siding or stucco sits on an uneven, sloped surface, which leaves the enclosure racked and opens gaps that channel water behind it. The MM-Series base gives you a flat, weathertight mounting surface on top of the siding, and its 1 inch overhang closes the gap at the perimeter so moisture stays out of the wall assembly. It is a backer and weather closure, not an electrical enclosure, so the socket and its connections are still per the socket manufacturer and code.
7) Is the Arlington MM meter base made in the USA?
Yes, the MM-Series meter mounting base is Arlington Industries domestic production, country of origin United States. That matters on government, school, and other publicly funded work where domestic sourcing is a condition of the contract.
8) Will a white meter base look out of place next to the other meters on my apartment building?
The MM-Series comes in white only, across all three sizes. On a building where the existing meter bank sits on unfinished siding or on mismatched plywood backers, running the same white base at every position is what makes the wall read consistent. If your exterior needs another color, this is not the part to specify.
