The Raptor 170 basketball unit has side swinging arms designed for play areas where the backboard needs to be swung out of the way when not in use. For example, on a tennis court where the basketball hoop would usually extend out above the service area.
The Raptor 170 extension arms hinges on a mounting plate which is bolted to the main pole. The twin arms allow the board to swing and remain parallel. Arms can be locked into position when in use and also when swung to the side.
