Have the ability to be tipped up onto their attached caster wheels and rolled away for easy storage. They feature an extension arm for easy tipping, 5″ non-marring caster wheels (rear wheels have a brake for securing movement when stored), rubber foot pads to prevent marring of indoor flooring and secure movement when in use and cross bracing on all understructure frame bays. An exclusive outrigger is standard on all 4 row Tip and Roll bleachers for added stability when in an upright position. Tip N’ Roll bleaches are also available in a Low-Rise system. Our “Preferred” Tip N’ Roll bleachers include (2) 2″x10″ foot planks. Since all 2 and 3 row Tip N’ Roll models and 3 and 4 row Low Rise Tip N’ Roll models are less than 30″ high, most codes do not require guardrail.
