ISC RP255 Medium Rigging Pulley

ISC RP255 Medium Rigging Pulley

The ISC RP255 Medium Rigging Pulley is part of the next generation of ISC 200 Series Rigging Pulleys. Designed and manufactured in the UK, this professional rigging pulley combines high-strength materials with ISC’s new Patent Pending SafeLock locking mechanism.

ISC developed the 200 Series to improve strength, reliability and ease of use. The RP255 uses hot forged high-strength aluminium frames with a redesigned shape. ISC used advanced stress analysis to redistribute material and maximise strength under load.

ISC RP255 Medium Rigging Pulley Features

The ISC RP255 Medium Rigging Pulley delivers several key design improvements:

• Part of the ISC 200 Series Rigging Pulley range
• Designed and manufactured in the UK
• Hot forged high-strength aluminium frame
• Redesigned frame for increased strength
• Heat-treated hardened stainless steel axle
• Unique axle and frame interlocking design
• Patent Pending SafeLock locking mechanism
• Low-profile locking system
• Quick-action locking mechanism
• Designed for demanding rigging applications

Stronger ISC Rigging Pulley Design

ISC completely redesigned the pulley plates to improve performance under load. The axle and frame also work together through a unique interlocking design. This helps reduce deformation and flexing under extreme loads.

The result is a 200 Series rigging pulley that ISC states can be up to 150% stronger than its predecessors. This makes the RP255 a strong choice for demanding professional rigging applications.

ISC SafeLock System

The new Patent Pending SafeLock mechanism builds on the trusted SpringLock design used across ISC pulleys. It combines quick operation with a low-profile design.

ISC has manufactured safety components and “Solutions in Metal” in North Wales for more than 50 years. The 200 Series reflects that experience, with careful attention to materials, construction and performance.

Always inspect rigging equipment before use. Follow the manufacturer’s instructions and ensure the pulley suits your intended application and rigging system.
