It is made of metal with two hinged wings to adjust to any vehicle with a hump.

It does not fasten in so it is free to move from one vehicle to another.

These were used in older cars and trucks for adding a CB radio, 8 track or Cassette to a vehicle.

Each wing is about 6 inches wide and radio mounding surface is also about 6 Inches wide.
