Mainsheetblock set complete Harken

The mainsheet block set consists of two Harken blocks. Both blocks are
ball-bearing and thus noticeably reduce the resistance. The upper block
includes a hook, for easy insertion and removal of the mainsheet. The block has
a height-adjustable curry clamp for covering the mainsheet. With a forged
shackle, the block is attached to the traveller. With the ratchet function,
which can be snapped in and out, the load can be reduced considerably and the
holding of the sheet is made easier. Depending on the boat type, the
translation is recommended as 7: 1, 8: 1 or 10: 1. The Harken blocks are
characterized by their very good workmanship and their excellent running
properties. We recommend using a mainsheet up to 10mm.

This set contains the two parts of a mainsheet block system and a 10mm
standard sheet.
