Mechanical flipline adjusters such as the Petzl Micrograb and Macrograb, Rockgrab, or SMC Grip offer reliable, consistent adjustment for flipline lanyards. 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.
Petzl's most popular flipline adjusters have an anodized aluminum body, cable spring to tension the ribbed cam, and install with included nylock nut. Ease of use and repair make this very popular.
The SMC Grip is a great rope grab which makes an excellent flipline adjuster on virtually any rope. The compact, sleek design of the Grip makes it easier to adjust, and the action is smooth and trouble-free as climbers have come to expect from SMC. Each Grip is hand-inspected before leaving the factory and made in the USA.
The folks at SMC build all their gear to last for 20 years of use, and you'll feel the attention to detail in the action and smooth design of the grip.

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 sued on metal rope means it is not to be used directly on steel cable. It is fine for use on steel-core fliplines.
Strengths listed are tensile strengths.
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.
