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 degrees.
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 degrees (typically for foreguy/afterguy) or 60 degrees (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.
Webbing blocks can be used in applications where swivel head and shackle attachment is not required, to achieve further weight savings.
Runner blocks, available in fixed head and swivel versions, have a unique cheek shape and guide rollers to help keep the line engaged with the sheave.
Shape and edge radii of central hole in hub are compatible with webbing fail-safe strops.
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.

Ball bearing exit pulleys provide fast, low friction performance for use with rope.
High Load versions of the Series 20 and 30 blocks have a solid bearing and wear resistant sheave Nylatron® for use with wire.
Narrow exit blocks such as RF452, RF453, RF568 and RF569 are typically used in dinghy spars for control lines such as outhauls. The external tabs can be formed to fit the spar profile before fastening.
The sheave of RF453 protrudes beyond the external tabs, allowing it to provide up to a 180° change of direction.
Upright lead blocks have many applications for line deflection and low profile leads above and below deck.
RF568 and RF569 exit blocks, when mounted in an inverted position, are frequently used as upright leads.
The term ′′pulley′′ and ′′block′′ can be interchanged.
For wire from 3/32′′ to 5/32′′.
These high load wire blocks are used for halyards, backstays, boom vangs and many other wire controls.
The RF103, RF104 and RF468 have flared cheeks to minimise chafing and removable sheaves for easy fitting and removal of the wire without cutting the termination.
