Buying Guide: Key Purchase Considerations
When selecting mounting blocks for exterior lights, consider the following factors to ensure a durable, code-compliant installation:
- Siding compatibility: Confirm the mounting block’s design matches your siding type and thickness (e.g., 1/2″ lap, double lap, vertical or horizontal).
- Built-in electrical box: A built-in box simplifies wiring and helps protect connections from moisture. Check the box capacity to accommodate your fixture’s wiring.
- Material and finish: Non-metallic options resist rust and corrosion; paintable finishes help with color matching for curb appeal.
- Weather resistance: UV rating and sealed enclosures reduce degradation from sun exposure and rain.
- Ease of installation: Look for one-piece designs or blocks with included hardware and simple mounting steps to minimize labor.
- Code compliance: UL-listed components and proper cable routing reduce electrical code concerns and safety risks.
- Future expansion: If you plan multiple fixtures, consider bulk packs or compatible variants to simplify upgrades.
For a balanced choice, prioritize mounting blocks with built-in electrical boxes for post-siding installations, ensure compatibility with your siding type, and select a finish that harmonizes with your home’s exterior. If you value versatility, a universal block with adjustable flanges and broad siding compatibility can reduce the need for multiple different blocks over time.
