5" Aft Leaning Modular Mount - Black

Seaview 5" Aft Leaning Modular Mount - Black

The Seaview PMA57M1BLK is a 5" tall, aft leaning modular radar mount designed for marine electronics installations where space and longevity matter. Compatible with 18"–24" closed dome radars, satdomes, and cameras, this mount properly elevates your electronics to eliminate interference and safely clear those on board.

Unlike conventional mounts, Seaview treats every high-grade aluminum component with Chem-Film (the same process used by Boeing) prior to applying a three-part epoxy prime and powder coat finish, delivering outstanding corrosion resistance suited to demanding marine environments. The compact 7"×7" base footprint minimizes deck footprint, while a single center hole provides a clean wiring point of entry. The hollow oval mast section simplifies cable management throughout the installation.

Seaview's robotic welding process — using a Lincoln Fanuc 55E Single Station, AM120iC/12L with a six-axis robotic arm and two-axis turntable — produces consistently superior welds, manufacturing mounts for stock, commercial, and military applications including OEM parts.

The modular architecture allows you to add optional accessories at any time, including spreaders and light bars for mounting navigation or deck lights, GPS antennas, and loudspeakers. When you upgrade your radar or satdome, simply replace the top plate rather than the entire mount — a cost-effective long-term solution. A Seaview Modular Top Plate is required and sold separately.

Follow the simple three-step selection system: 1. Pick Mount Style, 2. Select Top Plate, 3. Choose Accessories.
