Equipment weight is important when climbing rigging and ladders. The Miller ACF-TBBDP AirCore™ harness with D-rings & lumbar pad is designed with lightweight stretchable polyester and aluminum hardware making it up to 20% lighter than competitive products on the market. Aluminum hardware lasts longer than traditional steel fittings especially when exposed to abrasive outdoor elements. Padded lumbar and shoulder straps keep the wearer comfortable allowing for extended use and maximum productivity. A back-mounted sliding D-ring provides a connection point for safety lanyards and lines while the two side mounted D-rings allow anchors for tie backs to keep the user in position to their work piece. A removable belt lets the wearer customize their tools and accessories or choose to not use it at all, dependent on the task at hand. Designed to support a 400 lbs working load, the harness is secured with a quick connector on the chest strap. The leg straps are fitted with a sub-pelvic strap which clasps in place with tongue buckles and the entire system locks together with cam buckle shoulder straps, all of which are adjustable for that perfect fit.
