Mobile Ball Mount Adapter with Peak SlimLink - Locking - Open Box, 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).
Our Review
Peak Design Mobile Ball Mount Adapter (Locking, Open Box) — Upgrade Any RAM or Off-Road Mount to SlimLink
The gist: A weatherproof aluminum adapter that retrofits 1” or 20mm ball-socket mounts — RAM, Offroam, Tackform — with Peak Design’s fast one-hand SlimLink phone connection.
- SlimLink push-button release: Attach or remove the phone one-handed in portrait or landscape — no more fiddling with clamp screws while navigating or pulling up for a shot.
- Vibration isolator: Best-in-class silicone dampener protects phone internals from motorcycle and ATV vibration — critical for long off-road travel days.
- Weatherproof aluminum: Machined and anodized construction handles rain, salt air, and sun — built for boats, motorcycles, and overlanding rigs, not just car dashboards.
- Fits 1” or 20mm ball: Snaps into the most common third-party ball-socket systems already installed on bikes, trucks, and ATVs — no new bracket required.
B&H Photo confirms the locking variant includes the integrated silicone vibration isolator and weatherproof anodized aluminum construction for outdoor vehicle use.
Best for: Adventure travelers with existing RAM or Offroam ball mounts who want to add Peak Design’s one-hand SlimLink connection. Skip it if: you don’t have a Peak Design case or Universal Adapter (required for locking). Open-box runs ~$35–$45 — check the current price before buying.
