The Vented Model has mesh sides and a back mesh window(with removeable cover)for extra ventilation and visibility. The Canopy fits any Wheelchair or Scooter. The canopy itself is generic, but the mounting kit will vary slightly depending on the make and model of your Wheelchair or Scooter. When you receive your canopy, it will include all the parts that you need to mount it to your vehicle. It's great for getting to and from work, daily errands, waiting at the bus stop ... whenever you need it!
