Rope Grabs / Flipline Adjusters

Rope grabs make for great flipline adjusters. Rope grabs such as the Petzl Micrograb and Macrograb, Rockgrab, or SMC Grip offer reliable, consistent adjustment for flipline lanyards. These mechanical flipline adjusters will last longer than hip prusiks, are easily repaired, and are more resilient to accidental nicks and cuts. For quick-release versions of some of these rope grabs, see our rope grabs page.

Gibbs Klimair Flipline Adjuster


This flipline adjuster is designed for 1/2” rope, and travels and operates in either direction, effectively turning a double-snap flipline into a two-in-one flipline. The Klimair is compact and lightweight. Climbing with a two-in-one flipline is safer and allows the climber to bypass branches without being unsecured.

Note: the warning printed on the Klimair that it is not to be used on metal rope means it is not to be used directly on steel cable. It is fine for use on steel-core fliplines.

A great upgrade to the twisted clevises listed below, these forged-steel twisted clevises screw tight into a "locked" position to ensure your connection is extra secure. Often used to connect to a flipline adjuster, as the twist holds the adjuster in a horizontal position that is easier to adjust. Must be securely tightened before use. Made in France.
