The product is a used Saris Bike Beam Rear Bike Bicycle Rack Carrier Frame Extension Bar. This black adjustable bar has a maximum capacity of 1 bike and can be mounted on the frame of a car or truck. With a length of 25 inches and I believe adjusts to 29 inches, this Saris Bike Beam provides a secure and sturdy way to transport a bicycle on the rear of a vehicle. Does lock well and appears to be good. I don’t know really much about this product, so ask any questions necessary. Thanks
