Buying Guide
- Size and footprint — Choose a base whose width and height accommodate the meter and any attached accessories. Larger bases (like MM23) offer room for bigger fixtures, while compact bases (like MM10) fit tight spaces.
- Material and UV resistance — Plastic bases with UV stabilization resist color fading and cracking in sun-exposed areas. If outdoor weather is extreme, prioritize UV-stabilized, color-molded-through options.
- Mounting compatibility — Look for bases designed to work with common meter configurations and accessories. Some models include or support a Snap-On Trim Ring or built-in channels for securing fixtures.
- Durability and finish — A maintenance-free, molded-through color finish helps prevent chipping and fading. For visible exterior areas, consider color options that match or complement your siding or trim.
- Installation considerations — Some bases are easier to install with fewer fasteners or with included trim rings. Check whether a base requires additional hardware and the ease of mounting in your wall structure.
- Environmental fit — If you expect exposure to hose racks or large accessories, ensure the base can bear the extra load and has appropriate mounting strength.
Frequently Asked Questions
What is a meter base mounting block used for?
A meter base mounting block provides a stable surface to mount electrical meters and related accessories on exterior walls, ensuring secure attachment and weather resistance.
Which material is best for outdoor mounting bases?
High-quality plastic bases with UV stabilization are common; they resist sun exposure, fading, and cracking better than untreated materials.
How do I choose the right size?
Measure the meter and any accessories. Choose a base with sufficient width and height to allow mounting clearance and future additions.
Are color-molded-through bases better?
Yes. They maintain color throughout the material, reducing visible wear and avoiding surface coatings that can chip or fade.
Can I install these bases myself?
Many bases are designed for straightforward installation with standard tools, but confirm any project-specific requirements in the product description.
What should I avoid when selecting a base?
A base that is too small for the intended meter or that lacks UV stabilization may require replacement sooner due to weathering.
