A ground-set, retrievable friction saver from Petzl for arborist tie-ins.
The Petzl Eject is a friction saver designed to be installed and retrieved from the ground, giving tree climbers a clean anchor without climbing up to set it. It protects the bark and reduces friction on the climbing line.
On many jobs the slowest part of the climb is getting the first tie-in set. The Eject is designed to go up on your throw line and climbing rope so you can set a protected anchor in a high crotch without climbing to it first. When the job is done, it comes back down from the ground.
That makes it useful on big pruning jobs and when you want a high, clean anchor point from the start. Compare it with our other friction savers if you mainly install from in the tree.
Follow Petzl's instructions closely for installation, the climbing systems it is designed for, and retrieval. Confirm it is set correctly from the ground before you weight it. A friction saver is life-support gear: it must meet the applicable standard, be used within ANSI Z133 and be installed by a trained climber.
Inspect it before every use for wear, grooves, damage to moving parts and a clean, positive function. Retire it after a fall onto it or any damage.
Ground-set systems have more to get right than a simple sling. Practice on a low limb, learn how the Eject sits when it is installed correctly, and only climb on it once you are confident you can confirm a good set from the ground.
