🪢 Two wheels. One much smoother ride.
The SINGING ROCK Tandem Pulley is built for zip wires and Tyrolean traverses, with two stainless steel sheaves working together to help prevent twisting as you move along the line.
With sealed ball bearings in each sheave, a 25 kN strength rating and compatibility with textile rope up to 13 mm or steel cable up to 12 mm, it’s a solid choice for adventure applications.
And it isn't limited to ziplines either. The Tandem can also be used for rescue, work at height and other vertical applications.
Smooth, stable and ready to roll.
