The Antal OPF 50 mm Swivel Block (Model 00501) is engineered for high-performance sail handling where flexibility, alignment, and low friction are essential. It features a 50 mm composite fibre sheave running on a stainless‑steel hub assisted by Delrin bearings, delivering ultra‑smooth rope movement and minimal drag without need for lubrication. The one‑piece CNC‑machined aluminium frame is hard black anodised and Teflon‑coated, offering outstanding strength, corrosion resistance, and sleek styling.
At its top, a heavy‑duty HR stainless steel swivel shackle provides triple locking positions—swivel, longitudinal, and transverse—ensuring optimal alignment under varying load directions. With no assembly pins or screws, the block remains compact and lightweight, weighing only 140 g, yet supports a Safe Working Load (SWL) of 500 kg. It’s a premium choice for both racing and cruising sailors who demand reliable, low-maintenance deck hardware with superior performance.
