Large Area Group Search Kit - Our Chicago search line bags are engineered with 1000 denier nylon covered on the back.  The bottom of the bag is covered with poly-coated nylon to resist abrasion, cuts, and tears. All seams are triple sewn with a Tex 138 Nylon thread and comes standard with a breakaway adjustable shoulder strap and reflective trim. The large pocket on the back has 2 smaller pockets to hold hand tools or webbing for a jiffy harness. Our primary rope is 9.5mm Kevlar over poly, it has an 860°F heat rating and 5,500 lb tensile strength. It is available with markers and rings. This allows the firefighter to stay oriented to distance and direction. Personal search lines are also available. They can be made of 6mm Kevlar over poly rope or 7/16" 100% Kevlar tubular webbing. The standard length is 25' but they can be made to any length requested.
