ISC Heavy-Duty Prussik Pulley with Becket (Aluminium / Stainless Steel)
The ISC Heavy-Duty Prussik Pulley with Becket range is designed for demanding rope access, rescue, arborist, and industrial applications. Manufactured with tamper-proof rivets, these pulleys comply with CE EN 12278 (2007) and NFPA (1983) requirements and have been independently accredited in the UK by a third-party test house for exceptional strength and reliability.
Available with aluminium or stainless steel sheaves and a choice of bushings or roller bearings, the range can be tailored to suit different applications. Bushings are ideal for high-load, low-speed use, while roller bearings provide smoother operation for low-load, high-speed applications.
Each pulley features a fully load-rated becket, designed to accommodate a karabiner with full rotation, providing greater versatility for rigging, hauling, and rescue systems. All models are individually serial numbered for complete product traceability.
