Features
- 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.
- Head posts of swivel blocks can be locked at 0∞ or 90∞.
- 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.
- Removable becket pin allows lines to be spliced prior to fitting.
- Stand-up blocks have rubber support bases that relax to 90∞ (typically for foreguy/afterguy) or 60∞ (for halyard and other lead block applications).
- Halyard blocks have a removable pin for attachment to deck padeyes or the mast collar, providing a low lead aft to organisers or winches.
- Strop blocks suit direct attachment to Dyneema or similar strops for maximum weight saving and flexibility.
- Runner blocks have a unique cheek and guide rollers to help keep the line engaged with the sheave.
- Shape and edge radii of central hole in hub are compatible with fail-safe strops.
- Foot block base plate and hub section is machined in one piece from a single block of alloy, for maximum integrity. Mounting bolts are seated within the base plate and hub to minimise bending loads to prevent racking over of the block.
- Foot block cover plate can be removed for service access without removing the bolts thats secure the block to the deck..
