This block is an efficient choice for sailors who want stable line lead in areas with limited space. The stand-up design keeps the block upright under load, providing secure and controlled trimming in cockpit and deck-mounted systems. The construction features a 2-stage ball bearing system with low friction throughout the load range. A reinforced composite frame reduces weight and increases strength, while the sheave rotates easily on its axis under both static and dynamic loads. The block fits lines up to 8 mm and can be used in many types of control systems, such as mainsheet lead, trim blocks and small purchase systems. The swivel head provides flexible angling and easy adjustment for mounting. Its low weight and compact size make it suitable for dinghies and smaller keelboats, where efficient power transfer and low friction improve handling. The stand-up function ensures precise positioning, even under changing loads.

INSTRUCTIONS FOR USE Fasten the block with suitable screws or fittings. Make sure the swivel head is correctly oriented. Lead the line through the sheave without sharp bends, and check regularly for wear.
