Rope -- New England - KMIII - 7/16" - MAX Black w/ Yellow Tracer - 400'
KMIII Max static rope is a balanced construction consisting of a continuous filament polyester twill pattern cover over a unidirectional nylon core. KMIII Max is designed to be more abrasion resistent, and to significantly reduce drag.
TPT (Twill Pattern Technology) is our 1-over-1 sheath design that results in a lower coefficient of friction significantly reducing drag through protection. Want to know more? Click here.

The polyester cover is very flexible, absorbs less water, has lower stretch, and is more abrasion resistant than the nylon covers found on some static ropes. The polyester cover and nylon core are balanced during manufacturing to attain the ultimate in performance.
KMIII static rope is a balanced construction consisting of a continuous filament polyester cover braided over a unidirectional nylon core. KMIII is designed to meet the rigorous requirements associated with rescue and rappelling operations. KMIII is dual certified (CE & NFPA).
Very little degradation from UV, and can be used over long term if inspected regularly.
Polyester has good resistance to most chemicals, except 95% sulfric acid and strong alkalis at boil. Nylon will degrade with strong oxidizing agents, mineral acids, and 90% formic acid. Nylon may discolor when exposed to high levels of carbon dioxide.
Polyester has a melting point of 480˚F with progressive strength loss above temperatures of 300˚F. Nylon has a melting point of 460˚F with progressive strengh loss above 300˚F.
Good resistance to the passage of electrical current. However, dirt, surface contaminants, water entrapment, and the like can significantly affect dielectric properties. Extreme caution should be exercised any time a rope is in the proximity of live circuits.
Recommended D/d* ratio is 8:1. (*Sheave diameter to rope diameter)
No blanket safe working load (SWL) recommendations can be made for any line because SWL’s must be calculated based on application, conditions of use, and potential danger to personnel among other considerations. It is recommended that the end user establish working loads and safety factors based on best practices established by the end user’s industry; by professional judgment and personal experience; and after thorough assessment of all risks. The SWL is a guideline for the use of a rope in good condition for non-critical applications and should be reduced where life, limb, or valuable property is involved, or in cases of exceptional service such as shock loading, sustained loading, severe vibration, etc. The Cordage Institute specifies that the SWL of a rope shall be determined by dividing the Minimum Tensile Strength of the rope by a safety factor. The safety factor ranges from 5 to 12 for non-critical uses and is typically
set at 15 for life lines.
