Abstract
A pneumatic spreader for increasing the magnitude of a gap between a window or door of a motor vehicle and the vehicle body, to permit a tool to be inserted into and maneuvered through the gap. The spreader may comprise a hand operated squeeze bulb having a gas release valve and two inflatable flexible bladders inflated from the squeeze bulb through a manifolded gas supply conduit. Each bladder may be greater in length and width than in thickness, and may have an internal stiffener to facilitate initially inserting the bladder into the gap without causing the bladder to fold or roll during insertion.
