MAXIREACH pivoting extension booms are designed to increase the area of reach for source capture products such as the MAXAIR self supporting fume arms and vehicle exhaust equipment such as MAXIREEL hose reels or MAXIDROP hose drops. The extension booms help reach points which are distant from a wall or other mounting areas. Extension booms can also be use to support items such as welding wire feeders or to undersling hoses or cables in conjunction with their primary function. The swivel section of the extension booms is made of rolled steel pipe. The top and bottom of the pipe is adapted for a MAXIDRIVE fan or flanged duct connection. The extension beams are manufactured of heavy gauge steel tubing with a bearing swivel. Double pivot type extension booms are divided by a bearing hinge which allows the user to reach back under the extension boom.
