This ladder hoist pulley system makes hoisting materials to rooftops and scaffolding incredibly easy. Its smooth-running pulley works with ½ inch to 1 inch ropes, greatly reducing lifting effort and friction-related rope wear. Made of high-strength metal, it supports up to 500 pounds with a stable, non-slip, deformation-resistant design, safely lifting paint, tools, building materials and maintenance parts for construction and high-altitude work. The extended handle allows easy direction adjustment to avoid collisions with ladders or walls, enhancing on-site safety. With a clip-on mounting structure and included locking pins, it installs quickly on ladders without extra tools, perfect for frequent movement and emergency use. Its bright red color ensures high visibility on job sites, making it an ideal practical tool for roofing, exterior painting, electrical installation, property maintenance and garden aerial work.
