Lewmar 60mm Synchro Halyard Block – Black
The Lewmar Synchro 60mm Halyard Block is a dedicated single-sheave block designed for halyard applications where smooth, low-friction line handling under load is the priority. The halyard-specific head geometry is optimized for the lead angles and dynamic loads common at the mast, keeping the line running cleanly whether you’re hoisting or lowering sail.
Built on Lewmar’s Synchro platform, it combines a high-density free-spin bearing, stainless steel strap, and glass-fiber reinforced cheeks for reliable performance across a full season of sailing.

Parts Desk Insights
Best use case: This block is purpose-built for halyard duty — the head geometry is optimized for the lead angles you encounter at the mast, which makes it a better choice than a standard single block for halyard applications. It’s well matched to performance cruisers and racers running 5/16"–3/8" modern line on main, jib, or spinnaker halyards.
If your line is larger than 3/8" or your loads are heavier, step up to the 72mm Synchro Halyard Block. Confirm the attachment-point dimensions and available space at the mast before ordering — halyard blocks often live in tight quarters near the sheave box or mast base.
