Part Number:
- Exceptionally high strength-to-weight ratio.
- Captive ball bearings for side thrust loads require no side retainer plates, reducing weight and providing a wider bearing surface for the Torlon needle rollers.
- Side cheeks incorporating head structure and hub are precision machined as a single part from solid alloy, leaving material only where it contributes to the load carrying capacity of the block and eliminating the need for additional fasteners.
- Head posts of swivel blocks can be locked at 0∞ or 90∞.
- Removable becket pin allows lines to be spliced prior to fitting.
- Halyard blocks have a removable pin for attachment to deck padeyes or the mast collar, providing a low lead aft to organisers or winches.
- Shape and edge radii of central hole in hub are compatible with fail-safe strops.
- Stand-up blocks have rubber support bases that relax to 90∞ (typically for foreguy/afterguy) or 60∞ (for halyard and other lead block applications).
- Runner blocks have a unique cheek shape and guide rollers to help keep the line engaged with the sheave.
- Foot block base plate and hub section is machined in one piece from a single block of alloy, for maximum integrity, with mounting bolts seated within the base plate and hub to minimise bending loads and prevent racking over of the block.
- Foot block cover plate can be removed for service access without removing the bolts that secure the block to the deck.
- Strop blocks suit direct attachment to Dyneema or similarstrops for maximum weight saving and flexibility.
- Spreacher blocks can accomodate a second spinnaker sheet for sail changes or an outboard genoa sheet for reaching.

- Primary mainsheet, halyard and spinnaker systems on boats to 14m (46ft).
- Secondary mainsheet, vang blocks on boats to 15m (50ft).
- Permanent and running backstay systems on boats to 12m (40ft).
- General control line and lead block applications on larger yachts.

- Fully machined Alloy cheek plates.
- Alloy sheaves with captive ball races.
