You can't see the bracket in the first picture, but it helps hold the flap stiff since there will be a lot of mud or rocks coming off the tires. In the second picture you can see part of the thick aluminum bracket. I like the quality, good work Gatorback!
The attachment works after bending the metal to make it fit my 2016 f 250 You will have to bend the main bracket backwards about 20 degrees to be able to have the smaller bracket attach to the bed and have the main bracket mounted.
Very heavy duty flaps that actually stop road debris from damaging your vehicle. Installed excactlly as directions said. There’s actually a you tube video also that’s helpful.
