The RABK Aerial Mount Bracket is used to attach a standard aerial and a range of other products to your Rhino-Rack Heavy Duty bar. The use of a shake proof washer reduces the loosening of bolts due to vibration while driving on corrugated roads. The Aerial Mount Bracket is made from zinc plated mild steel so it won't corrode during extensive outdoor use. It is simple to fit and will ensure that your aerial is secured for all on and off-road activity.
