Tylaska's halyard shackles have the highest strength-to-weight
ratio of any existing halyard shackle on the market.
A captive 17-4PH stainless pin makes for trouble-free
operation. The all-metal machined line thimble allows
for use as a 2-1 purchase without the wear or melting
that occurs with plastic molded thimbles. Lines can
also be permanently spliced for a fixed halyard.
Tylaska CNC machines the 3D shackles from a solid block
of aluminum. Type III hard coat anodizing protects against
corrosion. Laser engraving identifies the product without
sacrifice to strength or risk of corrosion. A new generation
design of the H8 over our original H8 halyard shackles
further improves corrosion resistance and provides more
thimble bearing area for 2-1 applications. The cross
pin is made from 17-4PH to resist wear and bending.
The pin is made captive to prevent loss but still allows
the full throat width of the clevis. The size was made
to fit standard sail headboards without adding any unnecessary
weight. Strength was optimized by computer and then
verified by numerous "make and break" destructive
tests. Coming soon is our sheave type 2-1 halyard shackle!
