Fall arrester line PETZL
Absorbica-I Flex 150

Flex version with 150 cm elastic arm. Suitable for users weighing between 60 and 140 kg. Offers several connection possibilities for the harness, and can be used with different coupling devices.

Compact fall arrestor that does not hinder the user during transfer. Durable fabric bag with easy opening system protects the fall arrester from abrasion and dirt and makes it easy to inspect. 
For frequent engagement and disengagement, use a carabiner held in place with the String positioning accessory (included).For semi-permanent connection, use a Ring Open openable ring for optimal positioning.
Two connection options to the end of the loop, lockable carabiner or MGO Open carabiner with large gate opening. Made of polyester and nylon.
