Series 25 Ball Bearing HHL Lashing Orbit Block™Single sheave ball bearing high load block with becket hub option and lashing head.The Series 25 Ball Bearing Orbit Blocks™ deliver superior strength, reduced weight, and exceptional performance for high-demand dinghy and small boat applications.Designed with competitive sailors and performance boats in mind, these compact 25mm blocks are engineered to achieve the highest possible strength-to-weight ratio. Featuring Ronstan’s renowned high-compression strength acetal bearing system, the Series 25 BB Orbit Blocks are a lightweight yet durable solution, ideal for control line systems such as mainsheet and spinnaker sheet turning blocks, cunninghams, and cascading vangs on dinghies up to 4 metres.Each block has a stainless steel hub for versatile lashing attachments and through-sheave becket functionality, making them adaptable to a wide range of rigging setups. The hub accommodates up to 4mm (5/32") lashing and ensures maximum efficiency without compromising reliability.The range also includes a High Load (HHL) variant – the RF28109HL – which is equipped with a Grade 2205 stainless steel sheave and bearing race, paired with Grade 304 stainless steel ball bearings. These HHL blocks are purpose-built for high-load applications and are increasingly in demand for modern performance and foiling boats using small-diameter lines to carry significant loads.Features:<ul><li>2-stage ball bearing system.</li><li>Suits up to 8mm (5/16”) lines.</li><li>Hollow hub for becket take-off.</li><li>Lashing blocks suit up to 4mm (5/32”) lashing.</li></ul>Specifications:<ul style='box-sizing: border-box; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-variant-alternates: inherit; font-variant-position: inherit; font-variant-emoji: inherit; font-weight: 400; font-stretch: inherit; font-size: 14px; line-height: inherit; font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, "Helvetica Neue", Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol"; font-optical-sizing: inherit; font-size-adjust: inherit; font-kerning: inherit; font-feature-settings: inherit; font-variation-settings: inherit; margin: 0px; padding: 0px; vertical-align: baseline; list-style: inside disc; color: rgb(33, 37, 41); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;'><li style="box-sizing: border-box; border: 0px; font: inherit; margin: 15px 0px; padding: 0px; vertical-align: baseline; display: list-item; list-style-type: disc;">Max.
