Today on our 2011 Ford Explorer well be test fitting the Yakima Railgrab roof rack system using part numbers Y00409 and Y00138. With our vehicle equipped with the factory side rails and our roof rack system preassembled according to the fit kit instructions, well go ahead and fit them to the vehicle. Well begin by setting the front crossbar on top of the side rails. Well find a fixed location on both side rails and measure from that location back on the side rail. Well need to keep these identical as it will help the front crossbar to stay perpendicular with the side rails for ease of loading our accessories. With our front crossbar located in the same place on both side rails well simply tighten down the black Allen head bolt using the included Allen wrench with your roof rack system.
Now that our front crossbars secure well go ahead and move on to our rear crossbar. Again, well set it on top of the factory side rails. This time well need to do a measurement from the center of the front crossbar to the center of the rear crossbar. While doing this measurement, Yakimas maximum crossbar spread is 46 inches. Were going to go ahead and set ours to 30 inches to properly fit our accessories.
Now that our rear crossbar is in the correct location we can go ahead and repeat the tightening procedure, tightening the black Allen bolt with the included wrench. With all our towers tight our roof rack system is secured to the vehicle and were ready to load our accessories. That does it for the Yakima Railgrab roof rack system using part numbers Y00409 and Y00138 on our 2011 Ford Explorer.
