CMC Dynamic I-lanyards

Versatile and efficient, CMC Dynamic I-Lanyards are multipurpose tools and personal protective equipment designed for high-angle rope work and vertical progression. Ideal for rope access, arbor, rescue, and via ferrata, they provide flexible attachment options for professional applications including work positioning, fall arrest, aid climbing, passing deviations, connecting to anchors, attaching to highlines, equipment leashing, rescues, and pick-offs.

Dynamic I-Lanyards are available in 24 in (61 cm) and 30 in (76 cm) lengths. Both models are constructed from 11 mm Teufelberger Apex dynamic rope with a dry-treated core, selected for supple handling and high durability. The rope is assembled in a relaxed state to minimize variations, twists, and shrinkage over time, while making the lanyard easy to manipulate and load into devices such as a chest ascender.
