This TWXpert Work Position Lanyard With Rope Grab is a part of a device system. This type of system supports the worker on a elevated vertical surface, such as wall or pole. This allows them to work handsfree while leaning. The lanyard connects the worker to an anchor point in front of their body. Its 13mm kernmantle rope has the interior core protected by a woven exterior sheath designed to optimize strength, durability, and flexibility. The core fibers provide the tensile strength of the rope, while the sheath protects the core from abrasion during use.
