8.5mm Opera w/ UNICORE - BEAL
8.5mm Opera w/ UNICORE - BEAL
The Beal Opera 8.5mm UNICORE is the lightest single rope on the market. It is also certified as a half and twin rope and weighs only 48g per meter. The rope is made with technology that combines all of Beal's know-how: UNICORE technology, DRY COVER protection and the UIAA Water Repellent standard for the GOLDEN DRY version. This ultra-supple, ultralight rope will exceed the expectations of the most demanding sport climbers and alpinists with its low impact force. The Beal Opera is certified as a Single, Half, and Twin rope. Ideal for performance minded sport, trad, alpine and ice climbing.
Weight: 48 g/m
Impact force: Single 7.4kN, Half 5.5kN, Twin 8.6kN
UIAA falls: Single 5, Half 20, Twin 25

PROCESSES
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.
OUR TREATMENTS
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.
