Some grips loving carrying every tool that exists on their body while others don't mind asking to borrow tools from AC's or running back to the cart for whatever they need. For a dolly grip, this is the perfect balance of both worlds. I hate carrying tools on my belt but need to stay organized and efficient. This toolpouch for your dolly and fits great on the flat metal backs of fishers and chapmans. The powerful magnets pop on and off without scratching the paint. It can hold your silicone spray, a water bottle, tape measure, and any assortment of torpedo levels, camera wedges, lasers, wrenches, chalk holders, soap stone, baby pins, or whatever else you need at arm's length. I sold my original one when I switched to rigging but I bought another one after my first dolly grip day in years because it just makes life that much easier. You could make your own from wood and magnets, but this one looks sleek and professional.
