RAM MOUNTS Short Double Socket Arm for C‑size 1.5" Balls — Compact, Marine‑Grade Aluminum, Spring‑Loaded Sockets

RAM MOUNTS Short Double Socket Arm is a compact, heavy-duty articulating link that connects two C-size 1.5" balls for near-infinite positioning and precise viewing angles.

This short double socket arm is designed for riders, drivers, mariners, and professionals who need a reliable, low-profile linkage between two C-size 1.5" ball bases. Built from powder-coated marine-grade aluminum with internal spring-loaded sockets, the arm lets you set and lock a device at nearly any angle while resisting corrosion, vibration, and harsh conditions. Its compact length reduces leverage on mounts, making it a preferred choice where space is tight or where a stiffer connection is required.

How does this arm let me fine-tune the viewing angle?

The arm uses RAM's dual socket design with an internal spring that opens the end sockets so each 1.5" ball can be pivoted independently. Once positioned, the balls sit firmly in the sockets to hold your device steady even on rough surfaces. It’s ideal for pinpoint adjustments without overswing or drift.

• Spring-loaded sockets permit smooth pivoting and precise placement
• C-size 1.5" ball compatibility with common RAM bases and mounts
• Short length minimizes leverage for a firmer overall setup
• Powder-coated finish helps maintain friction and grip over time

What materials and finish protect the arm in marine or outdoor use?

The arm is constructed from marine-grade aluminum and finished with a durable powder-coat to resist salt, moisture, and UV exposure. Those choices reduce corrosion and wear compared with untreated metals, extending service life in demanding environments.

• Marine-grade aluminum resists rust and structural fatigue
• Powder coating adds UV and abrasion protection
• Solid construction suited for vibration-rich settings like boats and off-road vehicles

Which setups and devices are compatible with this short double socket arm?

Designed to work with RAM's C-size 1.5" ball ecosystem, the arm pairs with a wide range of bases, cradles, and device-specific mounts. Its compact reach makes it especially useful when mounting GPS units, phones, cameras, or small displays where space or pillar clearance is limited.

• Connects between two C-size 1.5" RAM balls or compatible aftermarket balls
• Common in marine consoles, motorcycle handlebar mounts, and dash installations
• Works well with RAM device cradles, camera adapters, and quick-release bases

How do I install and adjust the arm for the best stability?

Installation is straightforward: slip each ball into the arm’s spring-loaded sockets and tighten the ball clamps on your base or cradle as needed. For maximum stability, use short lever arms and ensure both ball clamps are torqued evenly; periodic inspection helps maintain optimal performance.

• Seat each 1.5" ball fully into the socket and verify spring action
• Tighten surrounding clamps or base hardware to recommended torque values
• Check and re-tension as part of routine maintenance after heavy use

Who this arm is for: This RAM MOUNTS Short Double Socket Arm suits boaters, motorcyclists, professional installers, and anyone needing a compact, corrosion-resistant articulating link between two C-size 1.5" balls. If you require secure, adjustable positioning in tight spaces or exposure-prone environments, this short arm offers a durable, low-profile solution that integrates with RAM’s wide mount ecosystem.
