Front Roll-Up for Trolley Skirt. Adds protection and security. Attaches by snap on straps for easy removal. Roll-up is designed to cover the trolley doors. Please make a note in Special Instructions if your trolley skirt is older than 1 year old. The current skirt design wraps around the corner of the trolley allowing the Rollup to meet at the corner edge. Older skirts do not wrap around the trolley corner and the roll-up would be too narrow.
