BEAL OPERA 8.5MM UNICORE

UNICORE

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 slips and gathers up over some usage. It then becomes impossible to pass this section of rope, whether ascending or descending.

THERMO FLUID

An infrared treatment which stabilizes the sheath fibers and therefore makes yarns more homogeneous. The result is a more compact, better handling rope.

DRY COVER

A process whereby every individual sheath strand receives a chemical treatment before the rope is manufactured. The treatment is hydrophobic, increases abrasion resistance, and is polymerised at high temperatures. The polymerisation process, together with every strand being coated individually, increases the life of the treatment. This treatment makes ropes more resistant to abrasion, repeated falls, heat, dust, moisture, etc and vastly increases their durability.

A DRY COVER treated rope is:

• More dust and moisture resistant.
• More abrasion resistant.
• Designed to maintain its suppleness in belay devices over time.

GOLDEN DRY

Process whereby every individual core and sheath strand is treated with a hydrophobic chemical formula before the rope is manufactured. The treatment is polymerised at high temperatures. This polymerisation process together with every strand being coated increases the longevity of the treatment. A GOLDEN DRY rope combines 2 treatments: the core’s treatment is added to the DRY COVER sheath treatment. This helps to achieve an astonishingly durable and waterproof rope.

A GOLDEN DRY rope:

• Is more frost and water resistant.
• Gains very little weight in humid conditions.
• Improves rope suppleness through carabiners and belay devices.
• Is more abrasion resistant during normal use

The GOLDEN DRY treatment allows ropes to be labelled as UIAA WATER REPELLENT.

UIAA WATER REPELLENT

The UIAA Standards testing submits a rope to light abrasion over its entire surface, equivalent to a few days of normal use. It is then soaked for 15 minutes following a precise measurement procedure. The amount of water absorbed must not be greater than 5% of the sample's weight. A rope that passes this test (in a certified laboratory) qualifies as "UIAA Water Repellent."

Beal's GOLDEN DRY ropes easily satisfy the UIAA requirements.

• In comparison: a non-treated rope absorbs around 50% of its weight in water during the same test. A rope labelled as "dry" but with inadequate treatments absorbs between 20% - 40% its weight in water.
• A Beal GOLDEN DRY rope absorbs less than 3% water. Only the "UIAA Water Repellent" certification guarantees performance.

BLACK LIMIT

Indelible black marking at the rope’s mid-point, on single ropes. All Beal dynamic single ropes benefit from the BLACK LIMIT middle marker, except indoor climbing ropes.
