Rohn RTP56 Top Plate Section R5 & R6

Top Plate Kit Designed for RSL Tower Sections R5 and R6
The Rohn RTP56 is a purpose-built top plate kit made for use with RSL tower Sections R5 and R6. This component installs directly onto the top closing angles provided with your tower kit, offering the structural cap needed for mounting thrust bearings or top mast accessories. The RTP56 ensures secure and reliable support for rotating masts and antenna assemblies in mid-height tower configurations.

Supports Thrust Bearings and RSL Top Mast Accessories
Pre-drilled to match the bolt patterns of TB3 and TB4 thrust bearings, the RTP56 also supports the RSLTMA Top Mast Assembly (sold separately). This compatibility allows for straightforward integration with rotating mast systems used in amateur radio, WISP, public safety, and broadcast communication towers. It ensures the top of your tower is fully prepped for directional signal applications and mast stabilization.

Mounts Securely to Closing Angles with Included Hardware
The RTP56 kit includes the steel top plate and all necessary mounting hardware to secure it directly to the top closing angles. Designed with precision hole alignment, it provides a quick, hassle-free installation that minimizes time on-site. Its clean fit and robust attachment system improve mechanical integrity at the tower’s most critical structural point.

Engineered for Outdoor Environments and Long-Term Use
Constructed from galvanized steel, the RTP56 is built to handle harsh conditions, including high winds, temperature swings, and corrosive environments. Whether installed in rural landscapes or coastal regions, the plate resists rust and deformation while maintaining solid performance over the life of the tower.

Ideal for RF, Utility, and Wireless Communication Towers
This top plate kit has become a trusted component in wireless internet towers, utility line telemetry systems, business radio infrastructure, E911 networks, and local broadcast towers. It supports applications where mast rotation and precise directional signal control are necessary—especially in locations where wind loading and height limits are critical.

Part of the Scalable Rohn RSL Modular Tower System
The RTP56 integrates seamlessly into the RSL tower platform, a system favored for its compact footprint and height efficiency. Its modular design enables contractors, engineers, and installers to expand towers in 10-foot increments while maintaining consistent mechanical performance at every level, including the top.
