ISC Progress Capture Pulley - 30kN – One Way Bearing

The ISC One-Way Locking Rescue Pulley range is designed for professional lifting, lowering, hauling, and tensioning applications where controlled descent and efficient lifting are essential. Available in Single (RP704) and Double (RP705) configurations, both models feature one-way locking bearings that provide maximum friction in one direction for controlled lowering, while allowing the wheels to run freely in the opposite direction to minimise friction during lifting, hauling, or tensioning.

Manufactured with durable anodised aluminium wheels and available in Red or Black, these pulleys deliver reliable performance in demanding rescue, rope access, and industrial environments. Each model is individually serial numbered for complete product traceability.
