Today we have with us a 2011 Ford Flex and we're going to be test fitting a Thule Square Load Bar Roof Rack System. We'll be using the 50 inch square load bars part number THLB58, the Traverse Foot Pack part number TH480, as well as the fit kit for our flex which is part number THKIT1518. We already have our load bar assemblies put together according to the instructions so now we're ready to mount them up on our vehicle. To do this first we'll open the passenger and driver's side front doors. We'll take our front load bar assembly and place it up on top. To position the front bar we need to measure 20-7/8 inches from the edge of our windshield to the leading edge of the Traverse Foot on either side of the vehicle.
Once we have the front bar in position we can use the included Acutight tools to tighten down the clamps. With the front load bar secured we'll close the doors and open the rear doors. We'll take our second load bar assembly and set it up on top of the roof. To position this bar correctly we need to measure 30 inches from the center of the front bar to the center of the rear bar. This measurement is known as the crossbar spread which is handy to have when shopping for accessories to fit your roof rack.
With the second bar into position we'll repeat the same procedure that we did up front to tighten and secure it to our vehicle. And with that done our roof rack is mounted to our vehicle and we're ready to start using accessories. That's it for our test fit of the Thule Roof Rack System using part numbers THLB58, TH480, and THKIT1518 on our 2011 Ford Flex.
