An incredible new PMI rope for Fire/Rescue professionals, the Classic Pro with Unicore® technology is now available in a 12.5mm (1/2”) diameter! 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.
