Like a mechanical third hand, this Mobile Device Holder, or ‘Mobi’ for short, securely holds your phone, GPS, VHF, EPIRB or other handheld mobile device anywhere you have installed a RAILBLAZA StarPort®, RibPort or RailMount. Spring-loaded arms with protective rubber grip pads adapt to a wide range of handheld equipment designs. Locking retaining strap combines minimal obstruction of device controls with convenient one-handed thumb release for fast access to the device itself. An alternative to the Adjustable Mobi (SKU 14272538), the fixed Low Profile Mobi works great in spots where space is limited. StarPort® mounts sold separately.
