Bowling Ball Ramp
This simple device is ideal for persons having limited use of legs or arms. The ramp is placed in front of the lane and the bowler need only give a slight push to roll the ball down towards the pins. It may be used in a standing position or from a wheelchair. The ramp is easily disassembled into three pieces for storage or transportation. Rubber tips at support-end and plastic scuff guards at opposite end protect floors. Made of durable chrome-plated steel. Measures 26" wide x 62" long x 25" high.
