This Anti-tipper for Karman S-Ergo 305 Wheelchairs comes in pairs and is used to add stability to the S-Ergo 305 line of wheelchairs, while not impeding mobility.
Anti-Tippers are a form of wheelchair stabilizer that prevent the chair from flipping over backwards under certain circumstances. Some have adjustable height, which changes how far back they allow the wheelchair to tip. All Anti-Tippers are easy to install, with no modifications needed.
