Wire Core Lanyard

A wire core lanyard is a positioning flipline with a steel cable core inside a rope cover, built to resist cuts when you work with a chainsaw on spurs. It is the standard choice for many climbers doing removals.

Why a wire core

When you're on spurs cutting with a saw, the lanyard is often right in the cut zone. A wire core lanyard has a steel cable inside the rope cover to add cut resistance, which is why many climbers use one for removals.

It is not cut-proof. A running saw can still cut through, so always use a second point of attachment while cutting. Compare all options in our fliplines and lanyards.

Wire core lanyards come in several lengths. A longer one goes around bigger trunks but has more tail to manage. Pick a length that suits the trees you climb most.

Setup and inspection

Wire core lanyards are stiffer than all-rope versions and work best with an adjuster made for them. Check that the adjuster and connectors are compatible with the lanyard's diameter.

Life-support gear must meet the applicable standard, follow ANSI Z133 and the manufacturer's instructions, be inspected before every climb, and be used only by trained climbers. Retire the lanyard if the cover is cut down to the wire, the core is kinked or bird-caged, or the terminations are damaged.

Check the cover for wear where it rubs bark and near the steel core terminations, since that is where damage usually starts. If you can feel the wire through the cover or see broken wires, retire it.
