Rohn JRM27510 Non-Penetrating Roof Mount

Non-Penetrating Roof Mount for Heavy-Duty Antenna Installations
The ROHN JRM27510 is a rugged, non-penetrating roof mount built for rooftop antenna systems requiring a secure and stable base without compromising the roof membrane. This model includes a 10-foot galvanized steel mast with a 2-7/8" outer diameter and heavy wall thickness, offering a reliable platform for larger and heavier antennas. Designed for use with concrete ballast blocks, it’s ideal for telecom, broadband, PCS, and wireless surveillance deployments.

Ballast-Based Design Protects Roof Membranes
This mount requires no drilling or permanent fasteners, making it perfect for use on flat rooftops where preserving the roof surface is critical. Instead of penetrating hardware, it uses standard 16" nominal concrete blocks (not included) to keep the base frame in place. This allows for strong, stable installations while ensuring compatibility with roof warranty requirements and long-term protection against leaks or water damage.

10-Foot Mast Height Offers Greater Line-of-Sight Performance
The included 10' mast provides substantial vertical clearance for improved signal transmission and obstacle avoidance. With a 2.88" outer diameter and a 0.203" wall thickness, the galvanized mast is built to handle mid-to-heavy antenna loads commonly used in wireless backhaul, point-to-point broadband, and cellular systems. Its extended height is ideal for rooftops with parapets or obstructions that limit signal path effectiveness.

5-Foot Square Base Frame Delivers Maximum Stability
The wide footprint of the steel base distributes weight evenly and accommodates up to 12 ballast blocks for enhanced wind resistance and stability. This ensures dependable performance in harsh outdoor environments, including high-wind and variable weather regions. The base is easy to assemble and provides a dependable platform without introducing stress to the building structure.

Ships Disassembled for Easy Transport and Quick Assembly
This unit ships in a disassembled format on a single skid, making it easier to maneuver into buildings with tight access or elevator constraints. All necessary mast and frame hardware is included for efficient setup on-site. Once assembled and properly ballasted, the mount forms a durable, professional-grade installation that is both secure and non-invasive.

Compatible with ROHN Accessories for Added Safety and Roof Protection
Installers can pair this mount with ROHN’s optional JRMMAT roof mat (1/8" thick) or JRMPAD (3/8" thick) to protect the roofing surface beneath the frame. For added safety in windy areas, the SCK150 safety cable kit (3/8" x 150') can be used to anchor the mast and prevent movement. These accessories help extend the longevity of both the mount and the roof.

Reliable Mounting Solution for Commercial Wireless Projects
From wireless internet providers and telecom integrators to security system contractors, this non-penetrating roof mount is trusted for reliable, secure installations. Its high-strength mast, ballast-supported base, and no-drill design make it a go-to product for mission-critical rooftop deployments where safety, performance, and compliance are all top priorities.
