Make large bleachers mobile with the Jiffy Mover System. This add-on is great for bleachers that need to be moved frequently like seasonal event seating, country fairground stadiums, and city park concerts. Once attached, one person can safely move large bleachers because the wheels stay with the bleacher and don't have to be put on every time. This jiffy system is designed to fit 10-row bleachers up to 27 feet long with top speeds of 5MPH. The Jiffy Mover System makes moving large bleachers a breeze with the hassle of lifting or matching up tongue and grooves.
