Altitude Work: This rope retractor manual pulley is designed for altitude work and helps with rope release, reducing labor when operating around exterior wall corners. Metal Construction: Made from strength metal material to deliver durable performance and wear resistance across different terrains. Rope Protection: Provides essential protection for fixed rope points, wear rock anchor points, and other abrasionprone areas, accommodating both thick and thin ropes. Adjustable Angle Mechanism: Features a groove wheel pulley that slides into place to guard ropes against sharp edges or coarse surfaces, suitable for complex environments. Use scenario 1: Exterior building maintenance at height, where rope control around corners improves safety and efficiency during rope release and positioning. Use scenario 2: Rope access or anchor work on rock faces or industrial sites with repeated wear, where rope protection extends rope life for both thick and thin lines. Use scenario 3: Work in environments with sharp or coarse surfaces, where the adjustable angle mechanism allows safe guiding of rope through difficult geometry without damage.
