Aluminum Alloy Pulley Block, Heavy Duty Single Rope Pulley Block for 12mm Rope, Climbing 26KN-LIAIKI

【Durable】This pulley is constructed from premium aluminum alloy, offering high strength, lightweight design, easy portability, rust resistance, high strength, and durability. 【High Strength】Sturdy and clearly marked, it can withstand a tensile force of approximately 26KN. The side plates prevent the rope from slipping, ensuring reliable safety while climbing. 【Stable and Smooth】Fine polishing ensures a smooth surface, providing smooth and rapid rotation to significantly reduce friction. The arc-shaped suspension point effectively reduces wear. Additionally, 6 cooling holes on the front and back help dissipate heat efficiently. 【Hole Diameter】 The small hole measures 12 mm, the large hole measures 14 mm, suitable for ropes with a diameter less than 12 mm. Internal concave pulley with a smooth surface. Perfect for climbing, also excellent for other uses such as transportation, hauling, etc. 【Inspection】 For safety, we recommend checking for cracks, deformations, erosion, etc., before each use. Check if the pulleys rotate smoothly and if they are worn. Check if the gap between the side plates is deformed, check if the pulleys are rubbing against the side plates, etc.
