NMP Sail Block - For 10mm rope
Part #NMP-S471818
Description
The NMP-S Block will be used for the mainsail reef.
Its feather weight combined with a huge MWL make this the ideal block for this use.
The NMP-S block also has an additional slot for attachment flat on the sail.
Dyneema® webbing is used to attach it to the sail. A little hand stitching through the outer slots will prevent the block from turning. The webbing should not be sewn closer than 2 x B to the block to lower the compression force.
