Very high-efficiency loss-resistant pulley

Openable even when attached to the anchor, the PRO pulley is designed for maximum simplicity when setting up hauling or load deviation systems. The side plate that locks under load, the large-diameter sheave and the very high efficiency sealed ball bearings make a pulley that is well suited for handling heavy loads.

The PRO pulley ensures maximum simplicity while setting up hauling or load deviation systems. It can be opened even while attached to the anchor. The side plate locks under load and remains attached to its connector, reducing the risk of losing the device.

The higher-diameter sheave, combined with the high-efficiency sealed ball bearings, make the PRO pulley a recommended option for handling heavy loads. It performs safely and reliably during rope access, rescue work, and other at-height applications.

Minimum rope diameter is 7mm while the maximum is 13mm. It has an efficiency of 95% and is certified for CE EN 12278.
