Petzl Sterno Chest Harness

Petzl Sterno Chest Harness

The Petzl Sterno Chest Harness is a lightweight shoulder strap system built to support ascent systems used with SRS (Stationary Rope System) climbing techniques. Designed for tree care professionals, it helps keep the ascent system correctly positioned during climbing while providing comfort, freedom of movement, and easy adjustment throughout the working day.

Support for efficient SRS climbing systems

The Sterno Chest Harness is designed to integrate with rope ascent systems, helping maintain the correct position of climbing equipment during SRS operations. By supporting the ascent system throughout the climbing process, it contributes to smoother and more efficient rope progression. Compatible with a range of tree care climbing setups, it offers arborists a practical solution for managing ascent equipment without restricting movement.

Ergonomic design focused on comfort

Slim, low-profile shoulder straps provide comfortable support without adding unnecessary bulk beneath outer clothing or climbing equipment. The straps are positioned wider across the shoulders to reduce pressure and minimise neck chafing during prolonged use. A floating front bridge improves mobility by allowing unrestricted upper body movement, making it easier to climb, position, and work comfortably within the canopy.

Adjustable fit for individual users

Multiple adjustment points allow the Sterno to adapt to different body shapes and climbing preferences. Rear adjustment buckles help achieve a secure fit, while three connection height options allow the ascent system to be positioned according to user requirements. Hybrid metal buckles can be fastened, released, and adjusted quickly, making the harness straightforward to put on, remove, and fine-tune throughout the day. Different colours on the inner and outer surfaces also help users quickly identify the correct orientation when fitting the harness.
