This model is designed to fit the RocknRoller R8RT, R10RT, R12RT & R16RT Multi-cart which many of you already own. Everyone knows that loading in long, hard and often round objects on a cart is a pain. They don't stack well and if they are longer than the cart. This could be c-stands, tripods, light and speaker stands, draping hardware, pipes, fabric rolls, trade show setups, etc. The GripnGaffÂ® Bag solves all these problems with ease. It is light weight but sturdy enough to handle anything you can put in it (well, maybe not machetes, or axes) but it certainly works with the gear used by shooters, gaffers, grips, audio techs, roadies and others in the business. It has cutouts where you attach shelves to your multi-cart. Load your cart with all your other gear in boxes, crates, camera bags, and audio gear, then put your c-stands, tripods, boom poles, etc into the GripnGaffÂ® Bag and easily get into buildings, through doors and into and out of elevators. When you're done, simply fold it and put it away. It will last for years of hard service. 30"Lx13.25"Diameter 12" handle sleeve.
