Our Retro Fit Flip-Up sign is designed to attach to an existing Headache rack on your pickup truck or used with the Barney Rack Headache rack.  This sign can be adjusted to several positions with the pivot and pin lock system. Using the handle, you pull the sign toward you to disengage the pin and pivot the sign to the desired position.  The sign has our gull wing configuration to help reduce wind resistance. The legs of the RF-Medium sign, from the bottom of the sign to the pivot point are 6”.
