The Singing Rock Phario Lite is a lightweight via ferrata energy absorber designed for users who prefer a low-weight setup for via ferrata routes and rope parks
Suitable for users weighing between 40 kg (without equipment) and 120 kg (including equipment), the Singing Rock Phario Lite combines compact construction with practical features for use on protected climbing routes.
The shock absorber webbing is folded into a compact hook-and-loop package that helps protect it from external influences. The absorber material is designed with very low water absorption to minimise changes in performance characteristics when used in wet conditions.
Attachment to a harness is achieved via a 15 mm tie-in loop, which can be connected using a cow hitch to harnesses commonly used for via ferrata and ropes course activities. The tie-in loop is constructed from HMPE fibres with a polyester outer layer to improve abrasion resistance.
The Singing Rock Phario Lite features 15 mm asymmetrical elastic arms with variable lengths. After attachment to the harness, the set measures 85 cm and extends to a maximum length of 130 cm on the longer arm. During product development, the elastic arms underwent 50,000 extension cycles.
Ergonomically shaped PALM Keylock carabiners conforming to EN 12275 Type K include wear indicators to help monitor carabiner condition. A central rest loop with a strength rating of 12 kN is integrated into the design, and a fall indicator label located inside the protective cover helps identify whether the energy absorber has been activated and requires replacement.
When fully deployed, the maximum braking length of the shock absorber is 170 cm.
