Ripcords, Cables, and Swages The standard ripcord used today on most parachute systems  consists of a stainless steel handle,  3 ⁄32" 7 × 7 corrosion  resistant steel cable, a stainless steel terminal ball, and one or  more stainless steel pins swaged onto the cable. The handles  come in various shapes and sizes in order to be compatible  with main lift web lengths and pocket sizes and particulars,  such as whether the ripcord grip is inboard or outboard. The  terminal ball may be of several configurations, such as a  Thus the term “push-pull system.” A compressible housing  compresses until it reaches its limit of compression, which  could be as much as 20 percent of the total length. In a  two-cable scenario, such as the 3-ring, the differential could  be as much as to allow the short side to release without  releasing the long side. Cutaway housings should be  measured in a relaxed state and then compressed to ensure  that it remains within the manufacturer’s allowable tolerance.  [ Figures 3-90A  through  3-92C] 3-24
