The Jiffy Mover System makes moving large bleachers fast and easy. The wheels, once attached, stay with the bleacher set so there isn't any hassle putting the wheels on and off every time the bleachers need to move. This prevents potential injuries or safety concerns and bleachers can be moved with ease by one person. This jiffy system is designed to fit 8-row bleachers ranging up to 15 feet long and 5MPH top speed. Make large bleachers mobile with the Jiffy Mover System, a great add-on to bleachers used for seasonal events, county fairgrounds, and city festivals.
