Rohn BRM445 Non-Penetrating Roof Mount

Built for Maximum Support on Flat Roofs
The Rohn BRM445 Non-Penetrating Roof Mount is engineered to handle substantial antenna loads while protecting the integrity of flat rooftops. Designed with a 36-inch tall mast and a 4-1/2 inch outer diameter, this mount delivers unmatched strength for heavy-duty antenna systems, satellite gear, and telecom infrastructure. Its rugged design ensures stability without drilling or damaging roofing surfaces, making it a go-to for professional and commercial installations.

Extra-Wide Mast for Demanding Installations
With a 4-1/2" O.D. mast, the BRM445 is built to accommodate larger and heavier antennas or mounting configurations. The added diameter increases structural rigidity and load-handling capability, giving you confidence in high-wind areas or when using oversized communication hardware. This roof mount supports various antenna types, from broadband and microwave dishes to heavy-duty cellular repeaters and broadcast systems.

Ballasted Mounting That Requires No Drilling
Ideal for locations where structural modification is not an option, the BRM445 uses a non-penetrating design with ballast trays sized to hold standard 16" concrete blocks (not included). This setup avoids the need for screws or bolts, ensuring your rooftop remains watertight and damage-free. The frame’s square base provides wide weight distribution for improved balance, making it ideal for long-term installations.

Hot-Dip Galvanized for Long-Term Durability
Durability is a key component in rooftop mounting applications, and the BRM445 delivers with its hot-dip galvanized steel construction. This protective coating defends against rust, corrosion, and weathering, even in coastal or industrial environments. Whether you're installing in extreme heat, snow, or salt-laden air, this mount is built for longevity.

Easy Setup with Professional Results
The mount ships unassembled to reduce freight cost and simplify transport, but it's quick to install using basic tools. Its wide-frame design makes ballast placement easy, and the mast is pre-fitted for fast connection. The BRM445 is compatible with most large-diameter antennas and mounting gear, offering flexibility across a range of deployment types.

Designed for High-Performance Antenna Systems
This roof mount is trusted by installers working in telecommunications, public safety, internet delivery, and broadcast industries. If your job requires secure, non-penetrating support for large mast installations on flat roofs, the Rohn BRM445 is ready to perform.
