The Guardian GR6 is so lightweight, youll almost forget you are wearing it. At a mere 1.7 lbs. and 3.3 X 2.5 X 2.5 in, the GR6 is the smallest and lightest SRL in its class - but weight is the only thing it gives up. The GR6s housing is constructed from UV-stabilized, high-strength polycarbonate/ABS and surrounds an incredibly strong steel load-bearing chassis. The sealed housing helps keep out dirt and other contaminants, providing extra protection for the internal components. Its HMPE webbing is ultra-lightweight and abrasion-resistant for a long life and is perfect for applications like solar that benefit from a more supple lifeline. Available with steel or aluminum snap or rebar hooks, the GR6 is a perfect fit in general industry, maintenance, and rebar applications.
