The R12 Bag V3.0 for Select RocknRoller Carts from GripnGaff is designed to carry equipment while attached to the cart's handle and can be used in the photo, video, and audio industries. The bag can carry light stands, tripods, microphone boompoles, and other equipment. The 12" sleeve on the side of the bag slips over the cart's handlebar, suspended over the side. The bag also has large cutout shelf holes, so you can still install a shelf on the cart. The bag is constructed of 1680D ballistic nylon and has durable machine stitching for strength. Additionally, the entire load of the bag is secured with its built-in cinch strap.
