RAM RAMD-201UC Short Double Socket Arm for 2.25″ Balls

Compact Arm for RAM’s Heavy-Duty 2.25″ Ball System

The RAM RAMD-201UC is a short double socket arm built for RAM’s D-series 2.25″ ball mounting system the heavy-duty tier of the RAM lineup designed for large, heavy marine electronics. It connects two 2.25″ ball bases, one at each end, and delivers RAM’s near-infinite angle adjustment in a compact form factor that keeps your display close to the mounting surface.

A single internal spring holds the sockets open for smooth pivoting during adjustment, then locks down firmly when tightened for a solid, low-flex hold. The short arm is the right choice when mounting space is tight or when you want minimal arm extension with maximum rigidity.

Key Features

• Short length ideal for tight mounting locations or minimal-extension installs
• Dual 2.25″ ball sockets, one at each end
• Spring-loaded sockets allow near-infinite angle adjustment
• Locks securely in position once tightened
• Heavy-duty D-series construction for large, heavy displays
• Note: This is an arm component only ball bases and device bracket sold separately

Compatibility & System Context

This arm is only compatible with RAM’s 2.25″ ball system (D-series). It is not interchangeable with 1″, 1.5″, or 2.5″ ball arms or bases. Pair it with the RAM RAMD-202U 2.5″ Round Base with 2.25″ Ball to build a complete surface mount.

If you need a 1.5″ ball short arm instead, see the RAM 1.5″ Ball Mount with Short Double Socket Arms. For a standard or long arm in the 1.5″ ball system, see the RAM RAM-201 Standard Length Double Socket Arm or the RAM RAM-111UD Long Arm Universal Mount Kit.

Parts Desk Insights

Best use case: This is the arm to recommend when a customer is running a D-series 2.25″ ball setup and needs a short reach common on flush-mounted or low-profile helm installs where the display sits close to the console surface. It’s also the right replacement arm when an existing D-series setup needs a new connector. Always confirm the customer’s bases are 2.25″ D-series before ordering this arm will not fit 1″, 1.5″, or 2.5″ ball bases. If they’re unsure, have them measure the ball diameter on their existing mount.
