This Spinnaker jammer block is for situations where a fixed foot block can't help: peeling spinnakers, or changing a sheet block. The plain bearing sheave provides smooth running at low loads and keeps excellent durability at high loads. The replacement webbing strop helps position the block on the toe rail or pad eye and give the fullest rotation for spinnaker sheet use.
The Spinlock Winch Feeders are low profile 25mm (1") solutions to divert lines from a clutch or jammer to an alternative winch.
