Chrome Plated, 3-WAY, MIRROR, RAIL or SIDE MOUNTS
The mounting clamp can be positioned horizonatally for horizontal mirror arms and rails, or vertically for vertical mirror arms or rails. The clamp may be omitted which will allow the angle bracket to be used as a side bracket on any flat vertical surface, such as the side of a motorhome or the back of a Jeep. The brackets are made from cold rolled steel and are finished with chrome plating. The K-6 does not include the antenna stud. The actual size of the bracket is 2.25" (57mm) wide by 2.9" (74mm) high. With the standard bolts supplied with the bracket, you can install it on a tube with a diameter up to 0.850" (22mm). If longer bolts are used, the maximum tube diameter is 1.5" (38mm).
1/2" hole fits any Firestick or Roadpro stud mount.
