WINDFRD Aluminum 1.5" Double Ball Mount with Two AMPS Round Plates

What buyers think

Buyer-review evidence for this mount is limited in the snippets available, but the recurring themes are clear. Owners describe the mount as solid and versatile for long-term use, with devices staying where they are set. There is also mention of a spring-loaded side feature that helps the setup stay tightened during rougher rides. Overall, the available feedback points to dependable positioning and sturdy day-to-day performance once installed.

What this mount is for

The WINDFRD aluminum 1.5" double ball mount is a multi-device positioning base. It’s designed to let you aim electronics at the angle you want, whether you’re working from a boat deck, a kayak or SUP setup, or a vehicle dashboard style location that provides a flat mounting plane. Typical use cases include tablets, phones, and fish finder screens, especially when you want the display oriented for glare reduction and comfortable viewing.

Key specs that matter for buying

Compatibility: 1.5 inch (C-size) ball and AMPS plates

This mount uses a 1.5 inch / 38 mm / C size double ball and socket arm system. That means it’s meant to work with 1.5 inch ball ecosystems and compatible device holders. It also includes two round mounting plates that support AMPS-style attachment for compatible holders, which is the part that determines whether your specific fish finder, tablet cradle, or screen mount will bolt on correctly.

Load capacity for real-world electronics

The mount is rated for up to 15.5 lb at rest and up to 4.5 lb at motion. In practice, that helps with common marine and mobile display weights, but it’s still important to stay within those limits and account for movement on boats or rough roads.

Material and corrosion resistance

It’s constructed from powder-coated marine-grade aluminum with stainless-steel hardware. It is salt spray tested for thousands of hours and uses stainless steel components to help resist corrosion in high-salt environments. If you’re mounting electronics where salt spray is common, that corrosion resistance focus is a big part of the value.

Ease of installation and adjustability

This is a drill-down mounting solution intended for direct installation onto a table, cart, desk, vehicle surface, or boat surface (any suitable flat surface). The package includes multiple sets of stainless-steel machine screws and lock nuts plus sheet metal screws, which supports different surface thicknesses and mounting approaches.

Once installed, the double ball and socket design is built for frequent angle changes. The practical benefit is keeping your screen or device aimed where you need it, without fighting tight pivot points.

Pros and cons, with buyer-fit context

Who this is best for

• You need a marine-leaning, corrosion-resistant base for fish finder or display setups.
• You already use, or plan to use, a 1.5 inch (C-size, 38 mm) ball and socket mount ecosystem.
• You want multi-angle positioning and don’t want your device orientation limited to a single fixed bracket angle.
• You prefer a permanent, drill-down mounting approach for a stable result.

Who should avoid it (or double-check first)

• You’re looking for a clamp-on solution or a non-drill install method.
• Your device uses a different mounting standard than AMPS-style round plates, or your system uses a different ball size than 1.5 inch (C-size, 38 mm).
• You need a quick-remove mount for frequent transitions between vehicles or locations.

Compatibility highlights for Garmin fish finders

The mount is listed as compatible with several Garmin models, including Striker series (Striker 4, Striker 4dv, Striker Plus 4cv, Striker Vivid 4cv), echo series units (echo 100, echo 150, echo 300c), and ECHOMAP Plus and UHD2 lines such as ECHOMAP Plus 42cv, 43cv, 44cv, 45cv, and ECHOMAP UHD2 6". If you have one of those Garmin models, this can simplify your path to a working hardware stack, but still confirm your specific mounting interface fits the plate and arm system you’re pairing it with.

Is it worth it?

If you want a durable, salt-friendly double ball mount with strong load ratings and genuine adjustability for a fish finder or display, this is a practical choice, especially for boat and vehicle installations. The value depends on one key decision: matching your device mounting interface (AMPS) and your existing ball/socket system size (1.5 inch / 38 mm C-size). If those align, you’re buying stability, adjustability, and a corrosion-resistant build meant for harsh environments.

Alternatives to consider

If you’re comparing options, consider alternatives based on what you prioritize:

• If you want less permanent installation, look for clamp or adhesive-based mounts in the vehicle or marine accessory category, but verify load capacity and vibration handling.
• If your setup uses a different ball size (for example, a different RAM-style ball standard), you may need a mount base that matches that size rather than forcing a conversion.
• If your device requires a different plate pattern or a non-AMPS device holder, focus on compatibility first, since the mount base alone cannot solve an interface mismatch.

FAQ

What does “1.5 inch / 38 mm / C size ball” mean for compatibility?

It refers to the ball-and-socket mounting standard used by this double mount. To make it work cleanly, your existing arm/base system should use the same 1.5 inch (C-size, 38 mm) ball size, and your device holder should match the AMPS plate interface provided for attachment.

What mounting surface types is this designed for?

It’s intended as a drill-down mount for flat surfaces such as a table, cart, desk, boat surface, or vehicle mounting location where you can securely fasten the base hardware.

What weight can the mount handle?

It’s rated up to 15.5 lb at rest and 4.5 lb at motion. Staying within those limits helps ensure the device remains positioned, especially when the vehicle or boat is moving.

Is it suitable for saltwater or marine environments?

The build uses powder-coated marine-grade aluminum and stainless-steel hardware, and it’s salt spray tested for thousands of hours to help resist corrosion. That makes it a better fit for marine electronics than standard indoor-only mounts.

Does it include the AMPS mounting plates?

Yes, the kit includes two round ball bases/AMPS round plate style mounting components so you can attach compatible device holders that use the AMPS hole pattern.

Which Garmin fish finder models are compatible?

Compatibility is listed for multiple Garmin models, including Striker 4 series and echo and ECHOMAP Plus/UHD2 lines, such as Striker 4, Striker 4dv, Striker Plus 4cv, Striker Vivid 4cv, echo 100, echo 150, echo 300c, ECHOMAP Plus 42cv through 45cv, and ECHOMAP UHD2 6".
