Description

The Ronstan Series 20 Ball Bearing HHL Lashing Orbit Block™ (RF25109HL) is a high-performance block designed for precision control and low-friction operation in dinghies, foiling craft, and small keelboats. Its HHL Lashing design provides versatile attachment options, allowing the block to be securely lashed to strops, rails, or eyelets while maintaining smooth line rotation.

Engineered with stainless steel ball bearings and a reinforced polymer sheave, the RF25109HL delivers consistent low-friction performance under dynamic loads. The Orbit Block™ design ensures clean line lead angles, minimising wear and maximising efficiency in complex control systems such as vang, outhaul, cunningham, and traveller setups.

Lightweight, durable, and corrosion-resistant, this block combines Ronstan’s precision engineering with practical functionality, making it an essential component for sailors demanding performance and reliability.
