2 inch nylon and Velcro® BLACK suspenders with interchangeable ends. Velcro®-backed vertical straps are adjustable and allow positioning of certain Duckbill modules anywhere on the vertical brace. Heavy duty engineered dorsal yoke distributes weight evenly and vertically rather than a straining shoulder and neck criss-cross design. Adjustable chest belt eliminates shoulder creep and allows an unbuckled belt to not lose tool load. Extra wide padded shoulder pads won't slide out of position. Non-metal suspender ends will never snap free of belt regardless of weight carried. Integrated yoke hook allows easy storage and retrieval. Models available with 3 rear struts for better weight distribution. Models available to work specifically with the 3M Turbo PAPR respirator system.
