ISC 14mm Compact Rigging Pulley Block

ISC 14mm Compact Rigging Pulley Block

The ISC 14mm Compact Rigging Pulley Block is part of the Next Generation 200 Series, designed and manufactured in the UK at ISC’s North Wales facility. Developed to enhance the trusted strength and reliability of ISC rigging pulleys, the 200 Series introduces structural improvements while retaining the performance professionals rely on.

Re-engineered forged aluminium frame

The pulley plates have been redesigned using advanced stress analysis tools. Material has been reshaped and redistributed within the hot forged high-strength aluminium frames to optimise performance under load. A unique axle and frame interlocking design, using heat-treated hardened stainless steel axles, reduces deformation and flex under extreme loads.

Patent pending SafeLock mechanism

The new SafeLock system builds upon the well-known ISC SpringLock mechanism. It maintains fast and intuitive operation while achieving a low profile design. The result is secure locking performance suitable for demanding rigging environments.

Compact size with high strength rating

Compatible with ropes up to 14 mm (9/16″), this compact pulley offers a minimum breaking strength of 100 kN and a working load limit of 20 kN. The anodised body is fitted with a grey pulley wheel and each unit is individually serial numbered. Weighing 610 g (1.3 lb), it provides a strong yet manageable solution for professional rigging tasks.
