The Jiffy Mover System is great for large bleachers that need to be moved frequently like fairground shows, park concerts, and seasonal events. The wheels are attached to the bleachers so moving is quick and easy without having to lift or fight with lining up the axles correctly. Mobility is so simple that one person can move a large bleacher rack by themselves. These wheels are designed to attach to 10-row bleachers that are 27 feet long and have a top speed of 5MPH. Don't stay stuck to a single spot, add the Jiffy Mover system to your bleachers to make large seating mobile!
