Strg Double Socket Swivel Arm for 1.5 in Ball Mounts - Versatile

In this review the Strg Double Socket Swivel Arm is examined for users who need a compact, highly adjustable arm for 1.5 in/C size/38mm ball mount systems. The single biggest reason to buy is its combination of near-infinite adjustability and tough, marine-grade construction, which makes it useful for electronics, fish finders and vehicle installations where positioning matters. The arm's 8.1 in overall length and ratchet-style 360-degree center rotation with a 180-degree swivel joint deliver reliable hold and repeatable angles in demanding environments.

Key Features

• Double socket design: Two 1.5 in sockets provide a wide range of motion so devices can be positioned precisely without complex adapters.
• 360-degree center rotation: Full rotation at the center joint makes it simple to reorient a mounted device quickly while underway or in tight spaces.
• 180-degree swivel joint: The swivel joint adds fine tilt control so viewing angles can be set to reduce glare or improve sightlines.
• Durable materials: Powder-coated, marine-grade high-strength composite resists corrosion and handles outdoor and wet use better than basic plastics.
• Compact length: An 8.1 in overall length with a 7.1 in socket-to-socket span keeps the setup compact while still offering useful reach for many mounts.
• Lifetime warranty: The included lifetime warranty gives confidence for long-term installations and professional use.

Who It's For

The Strg double socket arm is best for boaters mounting fish finders, vehicle owners or riders fitting GPS or cameras, and professionals who need a repeatable, corrosion-resistant mounting link for 1.5 in ball systems. Its near-infinite adjustability makes it a good choice when frequent repositioning or precise alignment is required.

Users who require unusually long reach or mounts for nonstandard ball sizes should look elsewhere; this arm is specifically built for 1.5 in/C size/38mm ball components and is optimized for compact setups rather than extended booms.

Pros & Cons

Pros
