Long-Reach Universal Mount Kit in Marine-Grade Aluminum
The RAM RAM-111UD is a complete, heavy-duty mounting kit built for installations that need extra reach and a wide mounting footprint. It combines a long 1.5" double socket arm with a 2.5" round AMPS base and a wide 6-1/4" x 2" rectangular plate — all constructed from powder-coated marine-grade aluminum for lasting corrosion resistance in saltwater environments.
The wide rectangular plate's multiple pre-drilled hole patterns — including the universal AMPS pattern — make it compatible with a broad range of marine electronics, radios, and gimbal-bracket devices right out of the box. The long arm gives you the reach to position displays further from the mounting surface, ideal for elevated consoles, T-tops, or offset mounting locations.
What's Included
- Long 1.5" double socket arm
- 2.5" round base with universal AMPS hole pattern
- 6-1/4" x 2" rectangular mounting plate with multiple pre-drilled hole patterns
Key Features
- Powder-coated marine-grade aluminum construction throughout
- Long arm provides extended reach for offset or elevated mounting positions
- Wide 6-1/4" x 2" plate fits marine GPS, chartplotters, CB radios, ham radios, gimbal brackets, and more
- Universal AMPS hole pattern on round base — compatible with the RAM RAP-403 Cable Manager for clean wiring
- Near-infinite angle adjustment with rubber ball-and-socket technology
Choosing the Right Arm Length
If you need less reach, the RAM RAP-111 with Standard Length Arm uses the same wide plate with a shorter arm. For the most compact option, see the RAM 1.5" Ball Mount with Short Double Socket Arms. If you need just the arm, the RAM RAM-201 Standard Length Double Socket Arm is available separately. For a compact kit with a smaller plate, see the RAM RAM-202-153-202 2.5" Ball Mount Kit with 1.5" x 3" Plate.
Parts Desk Insights
Best use case: This kit is the right call when a customer needs maximum reach and a wide plate — common on T-top installations, elevated helm stations, or anywhere the display needs to be pulled well away from the mounting surface. The marine-grade aluminum construction makes it the premium choice for saltwater boats where corrosion resistance matters. The wide plate's multi-pattern drilling gives the best chance of a direct device fit without adapters. Pair with the RAM RAP-403 Cable Manager to route wiring cleanly through the AMPS base.
