Rohn JRM35010 NonPpenetrating Roof Mount

Non-Penetrating Roof Mount for Heavy-Duty Antenna Support
The ROHN JRM35010 is a non-penetrating roof mount system engineered for rooftop antenna installations that require high mast strength without compromising the integrity of the building. This system includes a 10-foot galvanized steel mast with a large 3-1/2" outer diameter, built to handle heavier antennas and accessories. The 5-foot square base supports standard concrete block ballast and is ideal for commercial telecom, broadband, and wireless deployments.

Supports Large-Diameter Masts for High-Capacity Installations
Designed for applications requiring a 3.5" OD mast, this system provides the rigidity needed for larger microwave dishes, sector antennas, or other high-load equipment. The 10-foot height helps increase line-of-sight for improved signal quality while the durable galvanized mast construction ensures reliable support in demanding outdoor environments.

Ballast Design Eliminates the Need for Roof Penetration
This mounting solution does not require any drilling or roof penetrations. Instead, it uses up to 12 nominal 16" concrete blocks (not included) to securely anchor the base in place. This allows the mount to be installed on rooftops without damaging membranes, maintaining roof warranties, and reducing the risk of leaks or long-term water damage.

Stable 5-Foot Square Base Provides Strong Wind Resistance
The 62" x 62" base frame is built to distribute weight evenly across the rooftop and provide optimal stability in high-wind areas. When properly ballasted, the mount stays firmly in place, even in challenging weather conditions. The all-galvanized steel construction ensures excellent corrosion resistance, making it suitable for both temporary and long-term installations.

Ships Disassembled for Easier Job Site Handling and Transport
The JRM35010 ships broken down on a single skid and weighs approximately 50 lbs once fully assembled (excluding ballast). All mounting hardware is included in a hardware carton, streamlining the assembly process and minimizing onsite preparation. The modular design also simplifies transport to rooftops through standard doorways, elevators, or stairwells.

Add Protection and Security With Optional Accessories
To protect the roof surface beneath the base, the mount is compatible with the JRMMAT (1/8" thick) or JRMPAD (3/8" thick) roof mats. Each JRMMAT includes four interlocking 72" x 18" sections that create a 72" x 72" protective buffer. For installations in windy regions or critical infrastructure sites, the SCK150 safety cable kit (3/8" x 150') adds an additional layer of anchoring and security.

Ideal for Telecom, Broadcast, and Broadband Applications
This mount is widely used in rooftop deployments for cellular extension, wireless internet backhaul, fixed wireless access, and surveillance networks. With a large-diameter mast, non-penetrating design, and tool-friendly assembly, the JRM35010 delivers the strength and reliability professionals need for rooftop infrastructure without compromising the building structure.
