Rohn BRM635M Non-Penetrating Roof Mount

Non-Penetrating Roof Mount For Secure Antenna Installation
The Rohn BRM635M non-penetrating roof mount offers a secure and reliable way to install antennas or vertical structures without compromising your building's roof surface. Designed for use with a 3-1/2 inch outer diameter mast, this roof mount provides a stable support system for communication equipment, satellite dishes, or broadcast hardware. It’s ideal for locations where drilling into the roof is not an option, such as commercial buildings, rental properties, or waterproof membrane installations.

Ballast Mounting System Eliminates Roof Penetration
This non-penetrating mount is designed with a ballast tray system that accommodates standard 16" concrete blocks, providing the necessary counterweight to anchor the mount in place. The mount uses a square steel frame to keep everything secure while eliminating the need for lag bolts or screws that could damage the roof. Whether for temporary or long-term setups, the BRM635M delivers a damage-free, worry-free installation experience.

Durable Construction With Corrosion-Resistant Coating
Built for long-term performance in challenging environments, the BRM635M mount is hot-dip galvanized to protect against corrosion, rust, and weather exposure. Its rugged steel structure ensures years of reliable service, making it ideal for rooftop antenna installations exposed to high winds and environmental conditions. The mast height of 48 inches adds flexibility to antenna positioning and signal clarity.

Fast Setup And Minimal Tools Required
Installation is straightforward—just assemble the frame, add ballast blocks, and mount your equipment. The design minimizes the number of required bolted connections, making it fast to assemble while maintaining structural integrity. This mount ships unassembled for easier transport and storage, and it's sized to accommodate tight rooftop spaces.

Compatible With A Range Of Communication Systems
The BRM635M is commonly used in cellular, PCS, public safety, two-way radio, satellite, and broadband internet applications. The 3-1/2" O.D. mast supports a wide range of antenna sizes and types, giving you the flexibility to adapt this mount to many configurations.

Ideal For Temporary Or Permanent Installations
Whether you're setting up a temporary broadcast solution or installing a permanent system, this non-penetrating roof mount offers a cost-effective and practical option. Its no-drill setup preserves rooftop integrity, while the heavy-duty build ensures reliability for both short-term events and full-time infrastructure.
