freecat Siding Mounting Blocks 3-Pack for 1/2 in Double

The FreeCat 3-Pack 8141DBL siding mounting blocks are pre-formed, paintable mounting bases with built-in electrical boxes engineered to install outdoor lights and cameras flush on 1/2" double vinyl siding.

These mounting blocks give you a tidy, weather-resistant way to attach exterior fixtures where standard backs boxes won’t sit flush against lap siding. Molded for double 1/2" vinyl siding but compatible with several lap and flat surfaces, each unit includes the hardware and NM cable connector you need for a clean, code-aware installation. Their textured, paintable finish helps them blend into your home’s exterior while the integrated electrical box keeps wiring neat and serviceable.

How does the FreeCat block ensure a secure, weather-resistant fixture mount?

Designed specifically to match the thickness and profile of double 1/2" lap siding, the block creates a flush mounting surface that reduces gaps where water and drafts can enter. The built-in electrical box sits behind the fixture, protecting connections and making it easier to seal against moisture.

• Precision fit for double 1/2" vinyl siding to minimize gaps
• Integrated box keeps wiring protected and accessible
• Textured flange supports caulking and weatherproof seals
• Included screws and NM connector simplify installation

Will these mounting blocks work with siding types other than double vinyl?

Yes — while optimized for double 1/2" vinyl siding, the FreeCat 8141DBL also installs on T-111, HardiePlank lap siding and many flat surfaces. If you’re mounting on thicker or nonstandard siding, measure depth and surface profile first to confirm a flush fit.

• Compatible with T-111 and HardiePlank lap profiles
• Works on flat exterior surfaces where a flush base is needed
• Paintable finish allows color matching across materials
• Check thickness before installing on unusually thick siding

What electrical and mounting hardware come with the kit?

Each 3-pack ships with three mounting blocks, NM cable connectors and the screws required to fasten the block to siding and secure the fixture. The built-in electrical box meets common safety layouts so you can route and secure wiring without adding a separate back box after siding is in place.

• Three FreeCat 8141DBL mounting blocks per kit
• NM cable connectors included for secure cable entry
• Screws for mounting through the flange into sheathing or backing
• Integrated box reduces the need for additional electrical components

How easy is it to finish and disguise the mounting block to match my home?

The textured surface is formulated to accept exterior paint, letting you match the block to siding, trim or fixture color. Its low-profile flange and clean edges make it straightforward to caulk and blend into adjacent siding lines for a discreet, professional appearance.

• Textured face accepts exterior-grade paint for color matching
• Low-profile flange simplifies caulking and finishing work
• Durable construction resists outdoor wear and fading
• Black finish provides a neutral base if left unpainted

Who is this for? Homeowners, electricians, and contractors who need a reliable, code-friendly way to mount outdoor lighting, security cameras, doorbells or other fixtures on double 1/2" vinyl lap siding — and anyone who wants a paintable, weather-resistant solution that hides wiring and produces a neat exterior finish. If you require a flush mounting surface, integrated wiring protection, and a kit that includes the necessary hardware, the FreeCat 8141DBL 3-pack is built for that purpose.
