Sterling HollowBlock2 480mm



The Sterling Rope HollowBlock2 480mm sewn loop is a versatile friction cord meticulously crafted from 100% Technora fibre, renowned for its durability and grip. This redesigned product, reinforced with more durable aramid fibres, ensures enhanced resilience and longevity, guaranteeing reliable application performance. With a diameter of 6.8mm, it delivers increased abrasion resistance, making it ideal for use as a prusik or Klemheist knot on ropes of 7mm or larger. While perfect for progress capture tasks in hauling systems, it's essential to note that it's unsuitable for running or fall arrest applications. Additionally, it's crucial to avoid scenarios where the system might encounter slack or high fall factors, as the HollowBlock2 is not certified for such conditions.
