Description

【2-Pack for Heavy Duty Systems】: Get the ultimate matched pair for your heaviest projects. Each 50mm block is engineered to handle a massive Safe Working Load of 400kg (880 lbs). Perfect for setting up commercial gym cable crossovers, dual-point garage hoists, and demanding material handling.
【Lockable 360° Swivel Head】: Total control under load. Forged from Marine Grade T316 Stainless Steel, the swivel features a unique lock mechanism. Let it spin freely to prevent heavy ropes from twisting, or fix the directional angle by tightening the hex screw.
【Large 50mm Silent Sheave】: Minimum resistance, maximum fluidity. The extra-large 2-inch PA66 nylon wheel provides a larger turning radius, significantly reducing cable friction. This ensures a whisper-quiet glide, essential for high-weight workouts.
【Rust-Proof Reinforced Body】: Built for harsh environments. Combining a high-density PA66 Nylon body with a T316 Stainless Steel core, these blocks are completely corrosion-proof. Ideal for saltwater yacht rigging, tree work (arborist), or humid outdoor climates.
【Thick Rope Compatible (Up to 12mm)】: Ready for serious lines. The widened groove accommodates thick gym ropes, heavy wire cables, and synthetic winch lines up to 12mm (1/2 inch) in diameter, keeping your thickest lines tracking perfectly.
