Tethys 13mm Pulley By C.A.M.P

Product Information

This compact swing-side pulley is engineered for professionals who need quick rope loading and versatile rigging in lightweight systems. The rotating side plates allow ropes to be installed or removed easily, even while the pulley is connected to an anchor. Its oversized attachment point accommodates up to two karabiners, offering increased flexibility in complex setups.

Built for efficient hauling and progress capture, this pulley is fully prusik-minding and compatible with Prusik knots on both sides. It’s ideal for building MA systems, redirects, or lightweight mechanical advantage setups in rope access, arboriculture, and rescue operations.

The pulley features a self-lubricating bushing system that ensures smooth operation at low speeds and light loads. Constructed from high-strength aluminum alloy with a stainless steel axle, it offers durability and efficiency in a compact package.
