Rupp Backing Plate - Large

The Rupp Backing Plate – Large is a heavy-duty marine-grade component designed for secure antenna and accessory mounting on center console and offshore fishing boats. This backing plate is essential for anglers who understand the importance of stable hardware in the face of vibration, wave action, and salt spray.

Constructed from corrosion-resistant stainless steel, the Rupp Backing Plate is engineered to withstand harsh marine environments, including saltwater exposure and UV radiation. Its large format of 6 x 8 inches effectively distributes load across the boat's hardtop or cabin structure, preventing stress concentration that can lead to mounting failures.

Ideal for both DIY installers and professional marine technicians, this backing plate is perfect for mounting VHF antennas, GPS units, outriggers, or fighting chairs. Its design accommodates multi-bolt configurations commonly found on center console towers and hardtop frame assemblies, making it a reliable choice for high-vibration zones.
