The Matthews Studio Max is the absolute best menace arm available. Tired of working with the limitations of pipe booms and ratchet straps? The Max has a small footprint, can be tucked into a corner or flat against a wall, and will allow you to boom a 75 lb light 17.5ft on the horizontal and 20ft in height. Need to quickly change position? The Max can be easily rolled at full extension on a smooth surface. It's easy, it's fast and its's SAFE! The Max can also be used below the horizontal, place it on a roof and boom down into a window! Such a versatile tool that's why it won an Academy Award. The Max uses standard 25 lb weights for counterbalance and requires a 3 to 1 weight ratio for balance. Shotbags and Sandbags may also be used for counterweight. Now you can get a light anywhere you want it with the Max. Maximum horizontal extension is 16ft or 17.5ft with optional 6ft extension. The minimum height of 6'6" allows for moving thru doorways. Max can be used completely horizontal at a ceiling height of 10ft. Now that's a serious boom arm! Not just for rigging lights, the Max can be used for rigging Cameras, Frames and Props.
