Sterling Ropes HollowBlock2 6.8mm Sewn Prusik Loop

Sterling's bestselling friction hitch and autoblock has been redesigned with a stronger aramid fiber.

The 6.8 mm HollowBlock2 is made of 100% Technora fiber for increased abrasion resistance and improved durability. It's gripping ability comes from the unique hollow-braid construction, for use as a prusik or Klemheist knot on ropes 7 mm or larger.
