- Material and durability: The ring and shell are made of 304 stainless steel with a robust nylon groove. This construction is durable, wear-resistant, rust-proof and reliable, providing steady performance and comfortable use during work. - Strong load capacity and compatibility: The built-in pulley supports up to 300 kg and is suitable for ropes up to 7 mm in diameter. This makes it versatile for heavy-duty applications while maintaining compatibility with standard rope sizes. - 360 degree rotating top ring: The top ring rotates a full 360 degrees to minimize rope, cable or lead knots and tangles, helping to maintain smooth operation in complex setups. - No noise during use: Silent bearings on both sides ensure quiet operation, reducing disruption in training rooms, workshops, or work environments. Use scenarios - Gym and fitness equipment: Integrate with overhead cable stations or rope-based resistance systems to enable smooth, low-noise pulley work and reliably handle heavy loads during training sessions. - Industrial and workshop settings: Route and guide heavy cables or lifting lines on machinery with minimal noise, improving workflow efficiency and reducing wear on ropes. - Construction, outdoor, and DIY setups: Create temporary rope routes for rigging, lifting, or securing gear on job sites or events, using a durable, rust-resistant component designed for demanding use.
