The single block is a compact choice for dinghies and smaller boats where stable and lightweight line handling is desired. It provides efficient control in trimming and steering systems and performs well under both low and high loads. The sheave is made of acetal and runs on a 2-stage ball bearing system, which reduces friction and ensures smooth operation. The stainless steel center body makes the attachment reliable and contributes to long service life in a marine environment. The block is suitable for control systems such as mainsheet traveler, cunningham, and cascade vang and can be used with lines up to 8 mm. The eye in the center body allows flexible mounting in many types of rig setups. Its small size makes it ideal on the mast, boom, and deck, where space is limited. The construction provides stable line handling without unnecessary weight and is relevant for both cruising and racing sailors.

INSTRUCTIONS FOR USE Attach the block with suitable rope in the center eye. Ensure correct tension and free rotation before use. Replace the line or block if signs of wear appear.
