Dyneema shackles from Loop are made
from Gottifredi Maffioli compact braid 12 strand dyneema rope. The
benefit of using a rope shackle over a metal shackle is that it is
lightweight, strong and it will not cause damage to your boat like a
metal shackle would.
The dyneema shackles are very easy to open
by hand and do not require a shackle key.
