Function: 1. High strength: The swing is made of hot forged aluminum and magnesium alloy material, which is characterized by high strength and lightness, and is safe and convenient to use. 2. Triangular design: the whole suspension point is triangular, and the force is more uniform when hanging. And the thickness reaches 9,9 mm, the force is higher, and the pulling force is stronger. 3. Reduced friction: Effectively support the pulley to rotate at high speed, reduce the coefficient of friction during its movement, and ensure its rotation accuracy. 4. Finely polished: The rock climbing swing is finely polished to provide a glossy surface, ensuring a quick turn and significantly reducing friction. 5. Wide Application: This rotary safety device is widely used in rapid descent, expansion, speleology, crossing, aerial work, etc. Specification: Item Type: Spinner Swing Material: Aluminum and magnesium alloy Gross weight: 136 g/4,8 oz Pulling force: 30KN Scope of application: mountaineering, rock climbing, expansion, downhill, downhill, protection, etc. List of packages: 1 x Swing Spinner
