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.
