Peak Design Mobile Ball Mount Adapter — Locking SlimLink with Push-Button Release, Machined Aluminum

Peak Design's Mobile Ball Mount Adapter converts any 1" ball-and-socket phone mount into a SlimLink-locked, push-button-release phone holder built for rough rides and daily driving.

Replace or upgrade your existing 1" ball mount with a compact, machined-aluminum adapter that adds SlimLink magnetic/mechanical locking, a push-button phone release, and a vibration-isolating interface. Designed to work with Peak Design cases or the Universal Adapter (each sold separately), this adapter is compatible with third-party mounts on cars, trucks, motorcycles, ATVs and boats — giving you a more secure connection without adding bulk.

How does the adapter make my phone mount more secure?

The adapter uses Peak Design's SlimLink system to create a combined magnetic and mechanical lock that snaps into place and resists accidental detachment. A dedicated vibration isolator reduces harsh road shock, helping protect sensitive devices during bumpy travel.

• SlimLink magnetic/mechanical lock for a positive snap-fit
• Push-button release for controlled detachment
• Integrated vibration isolator to reduce impact and rattling
• Secure hold on uneven roads and outdoor terrain

Will this fit my current 1" ball-and-socket mount?

Yes — the adapter is engineered to mate with standard 1" ball mounts used across many aftermarket mounting systems. You keep your existing mount (sold separately) and add SlimLink capability without replacing the whole assembly.

• Works with third-party 1" ball mounts
• No need to buy a new base or swivel arm if it already uses a 1" ball
• Ideal for cars, trucks, motorcycles, ATVs and boats
• Simple threaded installation to existing ball hardware

What phone cases or adapters are required to use SlimLink?

SlimLink requires either a Peak Design phone case that includes SlimLink compatibility or the Peak Design Universal Adapter to convert other cases. Both options are sold separately, and either will let your phone engage the adapter's magnetic/mechanical interface.

• Peak Design cases: direct SlimLink compatibility
• Universal Adapter: works with nearly any case or bare phone
• Adapter clicks into place when paired with SlimLink-capable gear
• No charging or power connection needed — purely mechanical/magnetic

How durable and weather-resistant is the adapter?

Manufactured from machined anodized aluminum, the adapter is built to withstand outdoor use and daily wear. Its slim profile minimizes bulk while the corrosion-resistant finish and solid construction stand up to exposure from road spray and sunlight.

• Machined aluminum body for strength and low weight
• Anodized finish resists corrosion and surface wear
• Compact design cuts bulk but retains structural rigidity
• Suitable for regular outdoor and marine environments

Who is this for? The Peak Design Mobile Ball Mount Adapter suits riders and drivers who already own a 1" ball-and-socket mount and want a smarter, lighter, more secure way to carry a phone. It's ideal for commuters, motorcycle and boat owners, outdoor adventurers using ATVs, and anyone who wants a quick, tool-free push-button release combined with industry-leading vibration control. If you plan to use a Peak Design case or the Universal Adapter, this upgrade adds SlimLink locking without swapping your whole mounting system.
