Sewn cord products are becoming increasingly popular as they eliminate bulky knots without compromising strength. Sterling’s 8mm sewn cord products are offered in various rope styles and lengths and take the hassle out of tying knots.
The RIT 8mm cords are manufactured using Sterling’s high strength, abrasion resistant RIT 500. Renowned for its heat and abrasion resistance these prusiks feature an aramid sheath and polyester core kernmantle construction for great handling. These prusiks were designed to meet the needs of arbor professionals around the world, though they’re equally well suited to work on a tower, wind turbine or wood pole.
To insure that your Prusik cord moves and grips properly, the diameter relationship between the standing line and your Prusik loop diameter should follow the general rule of a 60-80% ratio. Proper guidelines recommend that you review your rescue applications and test any new cord prior to actual field use.
