Compression spring - for 12B
Details
Compression spring - for 12B. 18 mm x 5 mm ID. Spare spring for 12B and 12C gooseneck units.
This spring is used to prevent the adjustment screw of the kicking strap altering position when the sail/boom shakes.
The spring can also be used to provide a neat and simple way of adjusting the position of a winch drum on an RMG winch without removing the attachment screw. See the thumbnail sketch for details.
