Horizontal hoisting sling designed for semipermanent attachment to the Medevac II & IIA (#404 and #406) and the military Stokes-type litters.  Identical to the  #190 with the following exceptions; titanium lifting V-rings replace the stainless steel O-rings and the snap hooks are drilled for cotter pins.  After attaching the sling, cotter pins are inserted to secure the hooks in place. Heat shrinkable tubing is then placed over the cotter pins to prevent tampering.  All required parts are provided.  Approved for US Coast Guard (Aviation).
