With ultra-light construction and a compact profile, this pulley block keeps rope control efficient without adding bulk to your rig. The 20 mm sheave offers smooth operation in tight sheave clearances, while the single swivel reduces line snag for easier fore-and-aft rigging. By omitting the shackle, installation remains streamlined in tight layouts on small boats, yet you still retain flexibility for use on larger yachts when needed.
