Thisis a 16g steel mounting bracket that you can weld to the lower part of your fender when running a chopper fender on a big twin rigid frame. This mount is designed to match the style of the factory frame mount. long enough to trim to fit and cover a wide variety of fenders. make sure to weld corners once everything is fit up for your application. Tip: i like to make a little paper template and trim that to fit then transfer that on to the fender mount so you get a perfect fit the first time.
