Strop blocks suit direct attachment to Dyneema
®
or similar strops for
maximum weight saving and flexibility.
Runner blocks 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 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 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.
