DYNAMIC ROPES

Sterling Rope manufactures the highest performing dynamic ropes in the
industry. We make dynamic ropes for all professional applications including
mountain rescue, military mountain divisions, rope access, or tower climbing.
Each of these work or rescue applications may require movement during
which a fall might occur. In these situations, dynamic ropes by design have
the energy absorption (elongation) characteristics, strength, and handling to
provide the necessary fall protection.

The technical features that sets Sterling’s Marathon and Evolution dynamic
ropes apart is our superior abrasion resistant sheaths and innovative core
constructions. Each rope model feature round, balanced sheath and core
constructions making the ropes lighter, with low impact forces, excellent
handling qualities, zero sheath slippage, and most importantly our ropes
trademark - DryCore. This outstanding technical innovation central to all
Sterling ropes is a proprietary coating process applied to all core yarns which
inhibits moisture absorption, maintaining the yarns original strength and
elongation characteristics.

Sterling’s dynamic and static ropes have been tested by some of the world’s
most respected and reputable rescue trainers, professional guides and
climbers under some of the most extreme conditions on the planet through
our Product Development Test Program. Each single, half, and twin rope is
fully certified to UIAA & EN 892 standards and also meets military
specifications. No matter what application or situation you may encounter,
Sterling offers the “right rope” that will meet your agency standard
or requirements.
