Maximum Dynamic Load (MDL) – The
maximum load that the block will remain intact with repeated sheave
movement. Breaking Load – Load at which major
block failure is likely to occur. All double blocks 2 x single MDL and
triple blocks 3 x MDL
The 60mm dynamic block range was designed particularly for the sports
boat market it can be used in a variety of applications from jib sheet
to mainsheet systems. It has a large central hole for tie-on becket
requirements and the high quality design and engineering is noticeably
in a league of its own.
Allen's range of high performance
blocks use their patented dynamic bearing and ultra-strap technology.
The dynamic bearing system forms the basis of the inner bearing
system while the ultra-strap strip of stainless steel can be lashed
without the fear of line abrasion associated with blocks of tradition
The sheaves and cheeks are moulded from
advanced engineering polymers, which are all wrapped up in
meticulously designed stainless steel cheeks, adding strength to the
moulded components. This hives you a beautifully engineered high
performance block which easily handles maximum loads.
