Quick answer
The Quad Lock Ball Top Cap Adaptor lets you use your existing 1" or 20mm socket arm to create a secure phone mount—no tools required.
What makes the Ball Top Cap Adaptor different from other mounts?
Unlike dedicated vehicle mounts that replace your entire setup, the Ball Top Cap Adaptor works with the socket arm you already have. This means you keep your existing hardware and simply add Quad Lock's twist-lock or magnetic mounting capability. The trade-off is that you need a compatible 1" or 20mm ball socket arm—if your vehicle doesn't have one, this adaptor won't fit.
Is it easy to install?
Yes. The adaptor slides onto your existing ball socket arm and tightens without any tools. The familiar ball design makes it quick to attach. Once installed, you can use Quad Lock phone cases or the MAG Heads for magnetic attachment. The main limitation is that the adaptor adds a small amount of height to your mount, which may affect positioning in tight cabins.
Frequently asked questions
Will the Ball Top Cap Adaptor work with any vehicle mount?
It works with any mount that uses a standard 1" or 20mm ball socket arm. If your mount uses a different size or a proprietary attachment, it will not fit.
Can I use magnetic mounting with this adaptor?
Yes. You can attach Quad Lock MAG Heads to the adaptor for magnetic phone attachment. This adds convenience but requires a compatible magnetic phone case or adhesive plate.
Does the adaptor come with a phone case?
No. The Ball Top Cap Adaptor is sold separately. You need a Quad Lock phone case or universal adapter to attach your phone. Check your phone model for a compatible Quad Lock case before buying.
Is the adaptor suitable for off-road or heavy-duty use?
The adaptor is designed for secure mounting in vehicles, including trucks. However, extreme vibration or heavy impacts may affect stability. For demanding conditions, consider the Quad Lock Truck Kit which includes a more robust mount.
