Aluminum 1.5 in Double Ball Mount with Two AMPS Plates - Heavy Duty

In this review the Aluminum 1.5 in Double Ball Mount is presented as a heavy duty mounting solution for boaters, vehicle users and workstation setups who need strong, corrosion resistant support for tablets, fish finders and small displays. The single biggest reason to buy is the robust construction: a one-piece, powder-coated marine-grade aluminum base with 1.5 in C size balls and supplied stainless hardware that resists salt spray and holds larger electronics securely. It installs directly to any flat surface and ships with marine-grade screws, making it ready for maritime or mobile use.

Key Features

• Heavy Duty Capacity: The mount supports up to 15.5 lbs at rest and 4.5 lbs in motion, providing secure hold for larger tablets and fish finder units.
• Marine-Grade Construction: Cast in one piece of aluminum with powder coating and 316 stainless hardware for long-term corrosion resistance in salty environments.
• Universal Compatibility: The 1.5 in C size balls and AMPS round plates accept a wide range of holders compatible with RAM, Arkon and iBolt style interfaces.
• Complete Mounting Kit: Includes four sets of 316 stainless screws, lock nuts and sheet metal screws so the base can be drilled to a table, dash or deck without extra parts.
• Multi-Angle Adjustability: Double ball and double socket arm design allows near-infinite positioning for optimal viewing angles and device alignment.

Who It's For

This mount is ideal for anglers with chartplotters and echo units, vehicle owners needing a stable tablet or phone mount, and marine users who require corrosion tested hardware that will hold up in saltwater. It suits anyone who needs a fixed, drill-down solution rather than a temporary clamp or suction mount.

Those who should look elsewhere include users wanting quick-removal, tool-free mounts or very lightweight phone-only solutions where the 1.5 in C size hardware and heavier build are unnecessary; if portability and ultra-light weight are the priority, a smaller clamp-style mount may be a better fit.

Pros & Cons

Pros

• Solid, one-piece aluminum base and stainless hardware deliver excellent sturdiness and long-term durability.
• High weight capacity at rest supports larger devices like tablets and fish finders with confidence.
• Ships with marine-grade screws making installation straightforward for decks, consoles or desktops.

Cons

• The drill-down installation makes it less convenient for users who prefer a removable or clamp-mounted setup.
• At motion the working capacity is lower, so very heavy devices in rough conditions may need additional consideration.
