Material:Type III Parachute cord ,stainless steel buckle Color:green+black Size:7-9 inches in length Weight: 35g The History Parachute cord : Parachute cord (also paracord or 550 cord when referring to type-III paracord) is a lightweight nylon kernmantle rope originally used in the suspension lines of parachutes. This cord is useful for many other tasks and is now used as a general purpose utility cord by both military personnel and civilians. This versatile cord was even used by astronauts during the 82nd Space Shuttle mission to repair the Hubble Space Telescope This standard described six types: I, IA, II, IIA, III, IV.[4] Types IA and IIA have no core. Type III, a type commonly found in use, is nominally rated with a minimum breaking strength of 550 pounds, thus the nickname "550 cord". The US military specification for paracord gives strength and construction parameters to which the final product must conform, as well as requirements for packaging and marking. Although the standard contains specific denier figures for the sheath strands and inner yarns, there are no overall diameter requirements for the cord itself. The core (also known as the kern) consists of several yarns, the number is determined by the cord type, and each yarn is made up of two or three (commercial) or three (MIL-Spec) smaller nylon fibers twisted together.
