Westlake Royal Building Products Versetta Stone Accessory Box (Receptacle/Light Box)

Lightweight fiber-reinforced concrete accessory boxes that solve the plastic mounting block problem. At roughly 1-5 pounds per unit, these boxes match Versetta Stone panels exactly — same texture, same colors, same concrete construction. No more cheap plastic boxes ruining the look of manufactured stone veneer.

Skip these if you’re using vinyl siding or don’t care about the plastic look. This kit shines when you need electrical outlets or light fixtures that blend seamlessly with stone veneer. The fiber-reinforced concrete construction beats plastic mounting blocks hands down — stronger material that matches real manufactured stone texture exactly, unlike plastic or polyurethane faux stone alternatives.

Installation follows a straightforward adhesive mounting process. Trace the box opening on the wall surface. Prepare the penetration with appropriate flashing and waterproofing. Install surrounding Versetta Stone panels, leaving the traced opening for the box. Apply 3/8” beads of Versetta Stone Textured Finishing Adhesive to the back of the accessory box in an upside-down ‘U’ pattern. Press the accessory box firmly into the opening to achieve full adhesive contact. Hold or shim the box until the adhesive cures.

Do not use mortar for installation — this is an adhesive-based system. Make sure electricity is off during installation for electrical penetrations.

Weather Resistance and Long-Term Performance

The fiber-reinforced concrete construction withstands freezes, thaws, wind, and heat — exactly what Montana throws at exterior products. No painting, coating, or sealing required, which matters when you’re dealing with 100+ freeze-thaw cycles per year in most valleys.

The 50-year limited transferable warranty backs up the durability claims. Transferable once within the first 15 years, with transferee coverage limited to the remaining 15-year window from the original purchase date. Coverage includes product defects but does not cover labor for removal or installation.

The real advantage shows up after five Montana winters. Plastic mounting blocks crack, fade, and look cheaper every year. These concrete boxes age like the stone panels they match — developing character rather than degrading.

System compatibility extends across the Versetta Stone line, including Ledgestone, Tight-Cut, and Carved Block panel styles. They’re designed for wood-based structural panel sheathing and wood framing substrates.

Frequently Asked Questions

What makes these better than standard plastic mounting blocks?

The fiber-reinforced concrete matches manufactured stone texture exactly, unlike plastic or polyurethane alternatives. You get stronger material in concrete versus plastic, plus seamless integration with the Versetta system for consistent appearance.

Can these boxes be painted a different color?

The material is listed as “Paintable/Concrete”, but the product features specify no painting, coating, or sealing required. They’re designed to match the panel colors without additional finishing.

Do these work with other stone veneer systems?

The boxes are specifically designed for Westlake Royal Building Products (formerly Boral) Versetta Stone systems. Using them with other manufacturers’ stone veneer would require verifying dimensional and adhesive compatibility.

What’s included in each order?

Each order includes one (1) Manufactured Stone Accessory Box. The Versetta Stone Textured Finishing Adhesive needed for installation must be ordered separately.
