Firmetal 7x6 Heavy-Duty Shelf Brackets – 1100 lbs per Pair | Premium Alloy Mantel Brackets (Set of 2)

Meet the Firmetal 7 inch x 6 inch heavy-duty shelf brackets, designed to blend rugged performance with a clean, timeless look. This set of two is built to support substantial weight while maintaining precise 90-degree alignment, so your shelves sit level and solid.

Rugged construction you can rely on

Crafted from a die-cast high-grade alloy metal, these brackets are marketed as lifetime rust-free. The lightweight yet strong alloy offers a favorable weight-to-capacity ratio, delivering a resilient foundation for shelves, mantels, or countertop supports. The 7 x 6 inch footprint is tailored to fit shelves that are 8 to 10 inches deep—lumber boards are not included, giving you full control over the exact wood you choose.

One of the standout benefits is the 100% perfect 90-degree vertical angle, designed to resist bending or deformation over time. Paired with a matte black powder coating, the finish adds a classic, adaptable look that blends with farmhouse kitchens, garages, basements, or outdoor-ready setups.

Maximum capacity, practical versatility

Although conditions vary with wall type and mounting, the brackets are designed to hold up to 1100 pounds per pair. That makes them suitable for books, tools, or emergency storage items when mounted properly. They’re not just for shelves—use them as mantel brackets to add a sturdy, decorative touch to a fireplace or as countertop supports in a workshop or utility room.

To help you get started, the package includes G5 high-strength screws and anchors appropriate for different wall materials. With proper steps and a pre-mounted lumber board, you’ll achieve a stable, level setup that stands up to daily use.

Ideal for real-life setups

Think of a garage workspace where heavy tools rest on secure shelves, or a kitchen where a sturdy heirloom tray or bakeware finds a reliable home. The matte finish and durable profile also suit basement storage or outdoor storage nooks, where you want resilience and a seamless aesthetic. The combination of robust alloy, precision angle, and ready-to-install hardware gives you a flexible foundation for many projects.

What you’ll get and how to install

Set of 2 brackets with the included hardware gives you a straightforward path to upgrading an existing shelf or installing a new one. The durable coating protects against rust and wear, while the 7 x 6 inch size keeps your project balanced and proportionate. Whether used to support a countertop edge or to accent a mantel, these brackets offer a reliable, versatile option that adapts to your space.

Note: lumber boards are not included. Proper mounting on appropriate walls ensures optimal performance.
