Weighing only 48 grams per meter, the lightweight Beal Opera 8.5 mm x 70 m dry rope is a must-have for sport climbers and alpinists looking to save weight without sacrificing performance.


  • Unicore technology bonds rope sheath and core without affecting the rope's suppleness; if sheath is cut or torn, both sheath and core remain bonded
  • Each individual sheath strand features Dry Cover hydrophobic treatment; Dry Cover is polymerized at high temperatures for added dust, moisture and abrasion resistance
  • Features indelible black marking at the rope's midpoint
  • Certified as a single, half and twin rope


Note: Half and twin ropes are designed to be used in matching pairs (size, length and brand should match). Using a mismatched pair can cause excessive wear on the ropes, exposing you to a higher risk of rope failure. Never climb with only 1 half or twin rope, unless it has also been rated as a single rope.
