CMC Low-Angle Litter HarnessFEATURES Faster to use than tying a harness out of web, the Low Angle Litter Harness fits on the outside of the litter, delivering greater stability than connecting carabiners directly to the railing. Made of our 1 3 4 in (44 mm) flat web with a tensile strength of 44. 5 kN (10,000 lbf), the center strap provides an adjustable backup to the other legs. The two outside straps attach just below the railing to the cross bar on the sides of the litter.
