- **价格:** £50.73 [^1]
- **概述:** RAM-HOL-UN10-400U is a rugged mount that uses the RAM X-Grip cradle to expand and contract for large phones and phablets, with a spring-loaded X design and device tether for outdoor use. It's paired with the Tough-Claw base for tool-less clamping on rails/tubes and provides 360-degree rotation. This suits people mounting large phones to vehicle or equipment rails for use in bumpy or rugged environments.
- **最适合:** It has a large phone clamp range (1.75 to 4.5 width) and a Tough-Claw clamp range of 0.625 to 1.5 diameter, which supports higher device holding capacity than smaller X-Grip sizes for dashboard/rail mounting.
