Donald M.wrote a review of Yakima RailGrab Tower on December 28, 2010
Towers work great with the short clips on our 2010 Ford Flex. Just traveled 600 miles from the east coast to the mid-west with our yakima cargo box attached with our rail grab towers with no issues. It took about an hour to set up for the first time and figure out where the towers needed to be on this car but have no issues after the initial setup.
Would recommend to anyone looking to put racks up on a Flex!!!
