Siding Light Mounting Block for Vinyl Siding - 2 Pack

In this review of the Vapikirv siding light mounting block kit, the bottom line is simple: this is a practical, no-fuss solution for anyone mounting exterior lights on 1/2 in double lap vinyl siding. The kit's single biggest advantage is how quickly it converts an uneven siding surface into a stable, paintable backing with a built-in electrical box, making it ideal for a homeowner or installer who wants a tidy, weather-conscious installation without fabricating backing panels. Installation time and material choices are the primary reasons to consider it.

Key Features

• Durable Materials: Made from UV-rated plastic so the block resists sun degradation and can be painted to match siding or fixtures.
• Built-in Electrical Box: The integrated box gives a secure, code-friendly place for wiring without needing a separate substrate behind the siding.
• Quick Installation: The block is designed for fast mounting and comes with instructions to complete most installs in about 5 min per block.
• Drainage Consideration: A weep hole on the bottom allows trapped water to escape, reducing risk of rot or trapped moisture behind the block.
• Compatibility: Fits 4 in high vinyl siding with double 1/2 in lap profiles and also works with T-111, HardiePlank lap siding, and flat surfaces when sealed correctly.
• Complete Kit: Each 2-pack includes two NM cable connectors and 10 screws so installers have the basic hardware on hand.

Who It's For

This mounting block is best for homeowners, handymen, and small contractors who need a fast, neat way to mount exterior light fixtures on 1/2 in double lap vinyl siding. Because the blocks are paintable and UV-rated, they suit aesthetic installs where a matched finish is desired and where modest water management is needed.

Those who should look elsewhere include people working with siding profiles much larger than 4 in height or nonstandard lap widths unless they are prepared to trim or customize the block, and those requiring metal or specialty outdoor electrical enclosures for high-abuse applications.

Pros & Cons

• Easy to install and comes with connectors and screws to start work immediately.
• White, paintable surface blends with siding or light fixtures for a finished look.

• Integrated electrical box makes wiring and mounting straightforward.

Cons

• Sized for 4 in high, double 1/2 in lap siding; may require trimming for other siding heights or profiles.
• Plastic construction may not suit heavy-duty commercial or high-impact locations.

Our Verdict

Frequently Asked Questions

Will this fit my vinyl siding?
The block is made for 4 in height with double 1/2 in lap siding; if your profile differs you may need to trim or customize the block.

Can I paint the block to match my siding?
Yes, the white UV-rated plastic surface accepts paint so you can match the block to your siding or fixture color.

Does it manage water behind the block?
There is a weep hole at the bottom to let any water escape, and the top should be sealed to prevent water intrusion (leave the drainage hole open).
