The Antal OPF 50 mm Single Web Block (Model 00509) is engineered for high-efficiency operation in sailing systems where low friction and minimal decay are critical. Featuring a single 50 mm composite fibre sheave mounted on a stainless-steel hub with Delrin bearings, this block provides fluid rope movement, very low drag, and no requirement for lubrication. The frame is a precision CNC-machined, one-piece, hard black anodized aluminium component with Teflon coating, ensuring maximum strength and corrosion resistance.
Designed for ease of use and longevity, the OPF 50 Web Block omits assembly pins and screws, resulting in a sleek, lightweight profile. The integrated webbing bail allows seamless integration into webbing soft systems or dyneema loops, facilitating secure attachment while maintaining performance integrity. Weighing just 100 g, it supports a Safe Working Load (SWL) of 500 kg, making it an outstanding choice for both racing and cruising applications where performance and durability are essential.
