CLGR® Open Type Pulley Block Double Sheave With Hook, also known as Open Pulley With Hook, and Double Sheave Snatch Block.
This open type snatch block features two sheaves mounted side by side, allowing the rope or wire rope to be reeved multiple times for increased mechanical advantage.
The open type construction enables quick and easy rope insertion without threading, even when the block is suspended. Equipped with a sturdy hook for secure attachment, this block is widely used in construction, industrial lifting, towing, and marine rigging where higher load capacity and directional flexibility are required.
The galvanized finish provides reliable corrosion resistance and wear protection for long-lasting performance in tough environments.
Available in various sizes and working load limits to suit different application needs.
