Mobile Ball Mount Adapter with Peak SlimLink - Locking - Open Box, 20mm 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) — One-Hand Phone Mounting for Mobile Professionals
The gist: A weatherproof aluminum adapter that upgrades any 1” or 20mm ball-socket vehicle or desk mount with Peak Design’s fast SlimLink phone attachment — useful for field workers and commuters who mount phones constantly throughout the day.
- One-hand SlimLink release: Push-button attach and release in portrait or landscape — faster than any clamp mount when you’re moving between vehicle and office.
- Vibration dampening: Integrated silicone isolator prevents phone damage on rough commutes and field trips — relevant for anyone mounting phones on motorcycles or work vehicles.
- Anodized aluminum build: Weatherproof construction handles daily outdoor exposure without corrosion — stays functional across seasons.
- Broad compatibility: Fits 1” (RAM standard) and 20mm (Offroam/Tackform/67 Designs) ball sockets — slots into most existing vehicle mount setups without new hardware.
B&H Photo confirms the locking variant’s integrated silicone vibration isolator and machined anodized aluminum construction.
Best for: Remote workers and field professionals who mount a phone constantly throughout the day and want the fastest one-hand attach/release on an existing ball-socket mount. Skip it if: you don’t own a Peak Design case or Universal Adapter — both are required for the locking mechanism. Open-box runs ~$35–$45 — check the current price before buying.
