The GripnGaffÂ® Bag is designed for professionals in the Film, Video, Music and Audio industries. The bag makes loading difficult items, like C-stands, tripods, and lighting, mic and speaker stands, easy. The bag is made of military grade ballistic nylon and features a new and improved (tougher) hard plastic bottom and a built-in cinch strap at the top. This model is designed to fit the Filmtools Jr. with shelves 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, they make getting into elevators and through doors difficult. 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, axes or running chain saws) but it certainly works with the gear used by shooters, gaffers, grips, audio techs, roadies and others in the business. It even 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 up and put it away. It will last for years of hard service.
