PETZL Jag Pulley – High-Efficiency Double Pulley for 8–11 mm Ropes | 91% Efficiency

Overview

The PETZL Jag Pulley is a high-efficiency double pulley crafted for single ropes ranging from 8 to 11 mm. Its compact form—38 mm long, 70 mm tall, and 38 mm wide—keeps weight to about 120 g, making it a practical addition to rope-access kits. The swinging-side plate arrangement allows smooth placement along the rope and reduces the chance of losing the pulley when it isn’t clipped to a carabiner.

Design and integration

Designed to work with the JAG TRAXION blocker pulley, the Jag Pulley enables a 4:1 or 5:1 force demultiplication system when paired with compatible gear. The plate geometry and fixed-point design help anchor the unit in place and support quick rope work across dynamic setups. The pulley is mounted on sealed ball bearings, which contributes to smooth, reliable operation even under repeated use.

Materials and construction

Made from durable aluminum and polyamide, the Jag Pulley is built to withstand field conditions. Its France-made construction reflects PETZL's emphasis on quality, with a compact footprint that pairs well with other PETZL components in professional settings.

Use cases and scenarios

Whether you are conducting rope access work, performing technical rope systems in rescue scenarios, or training with multipliers, this pulley offers a dependable option for efficient material handling. Its compact size and robust design make it suitable for confined spaces and demanding environments. The combination with other PETZL gear helps you assemble multi-stage rigs that may reduce the manual load in complex setups.

Care and durability

Regular inspection of the bearings and plate alignment is recommended to maintain optimal performance. Store in a dry environment away from excessive heat to preserve the aluminum and polyamide components. The unit’s temperature tolerance supports a broad range of field conditions.
