Gemtor 543 Series Class II/Class III Harness


The Gemtor 543 Class II/Class III is a one-of-a-kind multi-functional harness that allows a user to convert from a Class II fire service harness to a Class III harness in seconds. It provides the wearer with excellent mobility and functionality along with the ability to increase the level of protection to suit the operation.

Class II Harness:
The Gemtor 543 Series Harness offers a combination of all of the great features found on Gemtor Class II harnesses, including a fixed front waist strap, front adjustments on the leg straps and easy-to-connect hardware. The A-frame includes a sliding D-ring to attach a personal escape system and a triple action aluminum carabiner/pompier hook.  The harness is constructed with sturdy 1¾" wide nylon webbing that is stitched with high strength nylon thread. The "Hybrid" style leg strap configuration combines the benefits of the Gemtor Class II harnesses with the wrap around leg strap from a rescue harness.

Class III Conversion:
The Class III harness conversion has attachment points at the sternum, two (2) on the A-frame (also called the handle) and a rear dorsal attachment point. All attachment points are tested and are rated to NFPA, OSHA and ANSI standards. The Class III conversion is available with plain shoulder straps or with the optional AirFlo 3D Comfort Breathable back/shoulder pad.
