The Beta Tools Tool Backpack & Trolley, No. C6T was designed for the professional tool-user who wants to stay mobile with their tools. Unlike a traditional tool bag that has a shoulder strap, the C6T backpack/trolley can be worn as a backpack but then quickly switch to trolley mode. The backpack straps conceal inside a large zipper pocket when not being used. The telescopic handle is spring-loaded and ejects with the push of a button. The C6T has heavy duty construction, which includes the industrial-strength zippers with oversized pulls and the rubberized bottom.
