back up reliability of a compatible reserve parachute. The packed system, ready to jump, measures
25 inches long by 15 inches wide by 7 inches thick.
The complete assembly consists of the TNT instructor harness and container assembly, a student
harness, the main deployment system, and the reserve deployment system.

1.4.1 TNT Main Harness/Container Description
1.4.1.1 Instructor Harness
The harness is made using type 7 webbing. The type 7 has a tensile strength of 6,000 lbs and is
integrated directly into the container. The “H” style harness provides more direct loading of the
harness to help prevent wear and stress caused by opening shock. The harness has integrated
reserve risers to ensure loads are evenly spread throughout the harness. During TSO overload
testing the harness/container withstood an opening shock loading of 23.5G or 14,100 lb without
breaking a single stitch.
The harness is secured to the instructor by three adjustable attachment points; one chest strap
and two leg straps. Additionally there are two main lift web adjustment points. The main lift web
adjustments are constructed using a two to one pull system and the hardware is designed for use
with type 7 webbing. These adjustment point and hardware choices ensure that users of all shapes
and sizes obtain a comfortable and secure fit.
