Got a Galaxy and a truck? Here’s how the Quad Lock Ball Top Cap Adaptor kit fits your setup, what it works with, and what to check before you buy.
Quick answer
If your truck has a 1-inch or 20mm socket arm mounting point, the Ball Top Cap Adaptor Truck Kit for Galaxy is a straightforward, tool-free way to secure your phone. It’s designed to combine with your existing setup, so check that you already have a compatible socket arm before ordering.
Why the ball design matters for truck mounting
The ball top cap uses a familiar ball-and-socket connection that lets you attach your Galaxy to a wide range of arms and mounts without special tools. That means you can often reuse hardware you already have—like a 1-inch or 20mm socket arm—rather than buying a whole new mounting system.
For truck owners, this is especially useful because cabs often have existing rails or arms from other devices. The adaptor lets you tap into that infrastructure with a simple twist-and-lock motion.
When this kit might not be the right fit
If your truck doesn’t already have a 1-inch or 20mm socket arm, this kit alone won’t give you a complete mounting solution—you’ll need to add a compatible arm or base. Also, if you prefer a magnetic attachment, you’d need to add a MAG head separately; the standard kit uses the twist-lock mechanism.
And while the ball top cap is versatile, it’s not a universal adapter for every ball size. Stick to the specified 1-inch or 20mm sizing to ensure a secure hold.
Fit and compatibility questions
- Will this work with my Galaxy S10e?
- The kit is listed under Galaxy S10e, so it’s intended for that model. However, the adaptor itself is a mounting interface—it doesn’t include a phone case. You’ll need a Quad Lock case or universal adaptor for your Galaxy to attach to the ball top cap. Check that you have a Quad Lock-compatible case or adaptor for your Galaxy before ordering.
- What if my truck already has a different ball size?
- This adaptor is designed for 1-inch or 20mm socket arms. If your existing arm uses a different ball diameter, it won’t fit securely. Measure your arm’s socket or check its specifications before purchasing. Measure your existing socket arm’s ball size to confirm compatibility.
- Can I use this with a magnetic mount?
- The standard kit uses a twist-lock mechanism, not magnets. However, you can add a Quad Lock MAG Head (sold separately) to convert to magnetic attachment if that’s your preference. Decide whether you want twist-lock or magnetic attachment before buying—magnetic requires an extra part.
- Do I need any tools to install it?
- No tools are required. The ball top cap installs quickly onto your existing socket arm, and your phone attaches with a simple twist. Installation is tool-free, so you can set it up in minutes.
- Is this a complete truck mount?
- No—this is an adaptor kit, not a full mount. It requires a 1-inch or 20mm socket arm (and a base to attach that arm to your truck) to function. If you’re starting from scratch, you’ll need additional components. If you don’t already have a socket arm and base, plan to buy them separately or choose a complete kit.
