Compact Universal Mount Kit in Marine-Grade Aluminum
The RAM RAM-111UB is the short-arm version of RAM's wide-plate 1.5" ball universal mount kit. It combines a short 1.5" double socket arm with a 2.5" round AMPS base and a wide 6-1/4" x 2" rectangular plate — all in powder-coated marine-grade aluminum — giving you a low-profile, corrosion-resistant mount that works across a broad range of marine electronics, radios, and gimbal-bracket devices.
The short arm keeps your display close to the mounting surface, making this kit ideal for flush consoles, tight helm stations, or anywhere you want a clean, minimal-extension install without sacrificing the wide plate's versatile device compatibility.
What's Included
- Short 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
- Short arm for low-profile, close-to-surface mounting
- 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
This is the most compact option in the 1.5" ball wide-plate aluminum kit family. If you need more reach, the RAM RAP-111 with Standard Length Arm (composite construction) offers a mid-length option, and the RAM RAM-111UD Long Arm Kit provides maximum extension in the same marine-grade aluminum build. For arm-only or base-only components, see the RAM RAM-201 Standard Length Double Socket Arm.
Parts Desk Insights
Best use case: This kit is the right call when a customer wants the wide-plate device compatibility and marine-grade aluminum durability, but needs the display to sit close to the surface — common on flush helm consoles, smaller boats with limited mounting depth, or installs where a long arm would feel top-heavy. The short arm also gives a stiffer, less flexible feel than longer arms, which some customers prefer for high-vibration applications. Pair with the RAM RAP-403 Cable Manager to route wiring cleanly through the AMPS base.
