Show your colors with PMI’s Old Glory. Made in the USA (of course) and certified to NFPA 1983-2017, this 12.5 mm rope is built for rescue. Unicore® technology creates the ultimate bond between sheath and core. This bond ensures sheath slippage is nearly zero, even when the sheath is entirely cut circumferentially. This rope allows the firefighter or rope technician to pass either a cut or torn sheath area, whether descending or ascending, since the sheath cannot bunch to create an impasse.
