Rohn RAL04 RSL Series Anchor Base Assembly - Section 4

Anchor Bolt Base Designed for Section 4 Tower Starts
The ROHN RAL04 is a purpose-built anchor bolt base engineered for installations where Section 4 of the RSL tower system begins at the foundation. Designed to provide a secure, level platform for modular tower construction, this anchor base ensures that your tower starts with accurate positioning and long-term structural dependability. It is a must-have component for professional-grade tower builds supporting communication, monitoring, or utility equipment.

Bolt Template Ensures Precise Anchor Placement
Included with the RAL04 is a pre-cut bolt placement template that guarantees the correct spacing and alignment for anchor bolts when embedding them into a concrete foundation. This ensures a perfect match with the tower section’s leg layout and prevents the need for field modifications or realignment during assembly. This is especially important when managing tight project timelines or strict height and alignment specifications.

Leveling Capability Built In for Perfect Alignment
One of the standout features of the RAL04 is its integrated double-nut leveling system. Once the concrete has cured, the base section can be adjusted using the upper and lower nuts on each anchor bolt. This allows the tower section to sit perfectly level, even if the foundation surface is slightly uneven. It provides a clean, reliable start for the rest of the tower stack and reduces stress on the structure over time.

Heavy-Duty Steel with Long-Lasting Galvanized Finish
Constructed from heavy-gauge steel and hot-dip galvanized to resist corrosion, the RAL04 is made to withstand the demands of long-term outdoor exposure. From high-humidity environments to desert climates, this base stands up to harsh conditions and provides lasting protection against rust, weathering, and physical wear.

Compatible with ROHN RSL Modular Tower System
This anchor base is fully compatible with the ROHN RSL tower system and is specifically designed to interface with Section 4 as the base segment. Its matching geometry and bolt pattern make it easy to integrate into new or existing RSL tower configurations, supporting efficient builds for telecom, SCADA, broadband, or surveillance projects.

Ideal for Professionals Requiring Structural Accuracy
For engineering teams, installers, and contractors who need fast, accurate, and weather-resistant foundation solutions, the RAL04 is a critical asset. It helps streamline the tower erection process while ensuring precise vertical alignment from the ground up.
