The WeatherBreaker is a canopy that attaches to wheelchairs or scooters to protect you from the sun and rain and fits any wheelchair or scooter. 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 will take you approximately 15-20 minutes to attach the two mounting poles to your wheelchair/scooter. These are black poles approximately 8" tall and less than an inch in width so they will not interfere with the normal operation of your wheelchair/scooter. Once the mounting poles are attached, then the canopy slips in and out. The Weatherbreaker Canopy comes in three unique models; the standard model, vented and maximum protection. The Vented Model has mesh material on the sides and back instead of solid fabric and provides more ventilation for heat protection while still sufficiently protecting from sunlight and rain. The Max Protection Model has the same mesh material as the Vented Model, with the addition of plastic drapes that cover your sides from the top of your canopy to the seat bottom to give you maximum protection. The plastic drapes slip over your canopy and are easily removable. Is compatible with Permobil F3 Corpus.
