Static Rope
In the last few years, more and more climbers understand the merits of static ropes for climbing situations. Static ropes offer big wall and expedition climbers a perfect low stretch, high strength rope for fixing, jumaring and hauling. Sterling Rope revolutionized static rope with the creation of its SuperStatic Rope, the original 48-carrier sheath in 7/16" and 1/2". Typical static ropes are made on 16- or 32- carrier machines with less twist in the cover yarns. These ropes have a much coarser, stiffer hand, exposing much of the yarn to abrasion -- a leading cause of early rope retirement. Sterling's unique sheath provides a more supple hand, making the rope easier to use. This sheath also reduces vibration allowing for more control while jumaring, and rappeling. And, with the 48-carrier sheath, less yarn is exposed to abrasion. With less bulk in the sheath, we can add more yarns to the core giving you a stronger rope. The other most significant difference between Sterling static and all others is DryCore™ Expedition, big wall and alpine climbers often expose their ropes to extreme wind, rain, and snow, with DryCore™, your rope will stay dry, supple, and strong longer.
HTP
This revolutionary new concept in static ropes offers notable advantages over nylon static ropes: extremely low elongation, less than 1% stretch per 300-pound load, greater durability, greater resistance to UV and chemicals, and the highest tensile strengths for their size.
Because they have 1/3 the stretch of nylon, HTP statics may be a better alternative for jumaring and hauling, reducing bounce and fatigue. Polyester is a stronger more durable fiber than nylon. HTP provides better protection from sharp rock, excessive jumaring, and rappelling on fixed lines.
Sterling offers two diameter ropes, the 3/8" (10 mm), and 7/16" (11.1 mm), for climbing applications. The 3/8" is a high strength, low stretch rope, ideal for anchors, lightweight fixing, and hauling or "tag" line. The 7/16" is better suited for climbing situations where there will be excessive amounts of heavy jumaring, hauling, and high exposure to sharp rock.
HTP Static is also available in 1/2" (12.7 mm), and 5/8" (16 mm). The 1/2" is a two person rescue/rappel rope. An amazing rope with a tensile strength of over 12,000 pounds! It's low elongation makes it perfect for rescue haul systems. 48-carrier sheath construction gives this rope super durability and suppleness. Appropriate for tower construction, short haul helicopter rescue, high angle technical rescue, and industrial safety applications. The 5/8" (16 mm) is the strongest life safety rope we make with over 15,000 pound tensile strength! A super heavy duty rope with a soft hand. Great for tower constructors, bridge work, utility and industrial safety applications.
