Rohn Products R4H RSL Section 4

Upper Tower Section for ROHN RSL Modular Systems
The ROHN R4H is the fourth-level structural section in the RSL Series tower lineup, engineered to extend tower height while maintaining integrity and strength. Built to exact ROHN specifications, this section features 2-3/4" U-style legs with 1/4" wall thickness and 1-1/4" outer diameter bracing. Designed for high-reliability applications in telecom, broadcasting, and wireless infrastructure, the R4H supports safe vertical stacking above lower RSL tower segments.

Designed for Modular Integration with Existing RSL Structures
Whether you're building a new tower or expanding an existing one, the R4H integrates directly into the ROHN RSL system. Its dimensions match perfectly with other RSL segments, ensuring secure connections without on-site modification. This standardized design speeds up installation and ensures load continuity throughout the tower structure.

Factory-Welded Bracing Ensures Structural Consistency
To streamline setup and maximize strength, the R4H includes factory-welded tubular bracing. The 1-1/4" OD braces provide excellent resistance against torsional forces and wind loads, helping stabilize antenna arrays, radio systems, and other mounted equipment. Welded connections reduce labor time while ensuring every section meets ROHN's strict quality standards.

Galvanized Steel Construction for Harsh Weather Protection
The R4H is built from hot-dip galvanized steel, offering protection against corrosion and environmental degradation. This makes it ideal for outdoor tower installations in high-moisture areas, coastal zones, or any climate with fluctuating temperatures. Long-term durability is critical for infrastructure that must perform uninterrupted year-round.

Ideal for Wireless, Emergency, and Data Network Towers
ROHN RSL towers are trusted by professionals across multiple industries, including telecommunications, public safety, energy, and internet service providers. The R4H section supports upper-level mounting for antennas, dish radios, and surveillance systems, and is used in everything from microwave links to SCADA networks.

Stackable and Scalable for Custom Tower Heights
The R4H is a key component in building scalable tower solutions. Contractors and engineers use this section to add vertical reach, boost signal transmission range, or support additional antennas on multi-user towers. It can be combined with base (R1H), mid (R2H, R3H), and upper sections for a complete installation.
