Beal - Joker 9.1 Unicore - Dry Cover
The Joker is made with Unicore, an astonishing process where the sheath and core are bonded without affecting the rope’s suppleness. If the sheath is cut or torn, the core and sheath remain bonded together, greatly increasing the safety margin of the rope. Check out the video for more info on this amazing feature.
Dry Cover treatment is applied to the sheath to make the rope more resistant to abrasion and to various attacks such as falls, overheating, humidity, mud and grit, and significantly increases their longevity.

Each filament of the sheath of Dry Cover ropes is treated with a water repellent chemical before the rope is manufactured. This chemical covering is polymerised at high temperature. The durability of this treatment is given by the polymerisation, but also because of the individual treatment of each filament before the rope is made. On a Dry Cover rope, the core is not treated.
• Improved resistance to grit and to humidity
• Limited water absorption
• Improved rope-running through karabiners and belay devices
• Improved abrasion resistance in normal climbing use.
ATTENTION : Used as single rope, this is not a rope to put in all hands, or in all belaying devices: Its thinness makes it a rope which absolutely demands an expert belayer. In effect, traditional belay devices will of fer reduced braking, and some automatic belay devices may not work at all.
• Ultra light and free running.
• The rope doesn't bunch up, and remains supple for the long term.
• Possesses all the advantages of the UNICORE technology.
Single: Very high level climbers.
Half or Twin: Climber / Mountaineer.
What is UNICORE® Technology ?
-- An astonishing process, bonding rope sheath and core without affecting the rope's suppleness.
-- If the sheath is cut or torn, the core and sheath remain bonded together.
-- With a standard rope, if the sheath is cut by abrasion over an edge, a frequent occurrence in the mountains, it slides and gathers over some metres.
-- It then becomes impossible to pass this zone, whether ascending or descending.
WARNING - Beal dynamic ropes are treated with a durable yarn cover to increase resistance to wear and humidity, and thus increase their active lifetime. When new, the braking effect of descenders and belaying devices is reduced. Before using the rope together with any friction device, check that the combination works effectively and securely to avoid any braking surprises.
