Lewmar's Synchro Control range is designed for hand held and cleated loads (i.e.. no winches). By combining MRT (Metal Replacement Technology) in the manufacture of their stiff cheeks and stainless steel central race, balls, and strap, Lewmar makes these blocks lightweight, long-lasting, and up to 40% more efficient that other budget blocks for mainsheet systems, resulting in better responsiveness and improved sailing performance. Their shackle switch adjusts from the swivel to fixed position easily.
Use the Synchro Blocks for heavy static loads in halyards, mainsheet systems, mast foot blocks, mast head blocks, and vangs.
