Petzl SPIN S1 High Efficiency Pulley

Description:

Possible to open, even when attached to the anchor, the SPIN S1 OPEN pulley is designed for maximum simplicity in setting up haul or load deviation systems and tensioned highlines. Compact, reducing weight and bulk, which is especially useful during technical rescue. The sheave with sealed ball bearings provides excellent efficiency. The swivel facilitates operations, allowing the pulley to be oriented under load and direct connection of carabiners, ropes, or slings.

Description

• Compact pulley designed for maximum simplicity in setting up haul or load deviation systems and tensioned highlines for work at height and technical rescue, when weight and size are important factors:
  - Triple-action opening of the moving side plate is quick and easy, even with gloves
  - The rope can be installed with the device connected to the anchor
  - Red indicator provides a visual warning when the moving side plate is unlocked
  - Special side plate design protects the rope path
