Mobile Ball Mount Adapter with Peak SlimLink - Locking, 1 Inch Ball
Ideal for motorcycles, cars, trucks, ATVs, overlanding vehicles, boats, planes, and wheelchairs, these adapters let you upgrade your 3rd party phone mount with Peak Design's strong, low-profile, easy-to-use SlimLink™ connection system. It works with a variety of modular 3rd party phone mounting systems—specifically ones that utilize either 1" or 20mm diameter ball-and-socket joints. These 3rd party systems enable an almost infinite range of mounting phone configurations. The Peak Design Ball Mount Adapters upgrade your system with brilliantly fast and secure mounting action for your phone. They also feature weatherproof machined and anodized aluminum construction, ideal for the Locking Ball Mount and all of the outdoor adventures you will go on.
Locking mounts are more secure, featuring push-button phone release, and are suited for outdoor use (motorcycles, dirtbikes, ATVs, boats). Locking mounts feature a best-in-class vibration isolator to prevent phone damage.
Requires a 3rd party phone mount that utilizes 1" (like RAM) or 20mm (like Offroam, Tackform, 67 Designs) ball-and-socket connection joints (sold separately). Locking mounts require a Peak Design Case or Universal Adapter (sold separately).

Peak Design Mobile Ball Mount Adapter — Locking, 1” Ball
The gist: The standard locking SlimLink adapter for RAM-style 1” ball mounts — brings Peak Design’s one-hand phone release to the most popular vehicle mount ball size in the adventure travel world.
- 1” ball compatibility: Fits RAM Mounts — the de facto standard across motorcycles, cars, trucks, and boats worldwide — no replacing your existing RAM arm.
- SlimLink push-button release: One-hand phone attach and detach in portrait or landscape — switches between navigation and camera use in under a second.
- Vibration isolator: Integrated silicone dampener absorbs road vibration from motorcycles and rough roads — protects gyroscope and camera components over long riding days.
- Weatherproof aluminum: Machined, anodized construction handles sun, rain, and sea spray — built for overlanding and coastal adventures, not just city driving.
B&H Photo lists this SKU (M-MM-AD-BK-1) as the 1” locking ball adapter for RAM-compatible mounts with confirmed silicone vibration isolator and anodized aluminum build.
Best for: Travelers with RAM mount systems on bikes or vehicles who want to add fast SlimLink phone connection without replacing their existing arms. Skip it if: your ball mount is 20mm (use the 20mm variant) or you don’t own a Peak Design case or Universal Adapter. Runs ~$25 — check the current price before buying.
