Petzl Sterno

The Petzl Sterno shoulder straps are designed to position and hold an ascent system in place when using the SRS technique (Single Rope System), specifically for professional tree care. The wide spacing on the shoulders prevents pressure on the neck and ensures comfort, even during long periods of use. The slim, unobtrusive design allows the straps to be worn easily under a work vest. The movable front bridge provides optimal freedom of movement during climbing and positioning tasks. Three connection heights enable a precise fit. The adjustable hybrid metal buckles are easy to open and close, making putting the shoulder straps on and taking them off quick and efficient. Note: the Sterno is not personal protective equipment (PPE).

Ergonomic design
The straps are colour-coded on the inside and outside, ensuring correct positioning at a glance. Rear adjustment buckles allow the straps to be adapted to different body types. Three connection heights make precise, user-specific adjustment possible.

Comfort and freedom of movement
The slim, low-profile straps are set wide across the shoulders to minimise pressure points and neck chafing. The movable front bridge enables natural movement during climbing and positioning.
