WARNING! Harken does not recommend drilling boat's chainplate
or toggle as this may result in rig failure which will cause an accident,
damage to your vessel, personal injury, or death. See www.harken.
com for additional safety information.
Will drum fit on bow? See page 7. If necessary use an additional toggle
to slightly raise the unit. To clear anchor use Harken Long Link Plates,
which can be cut to various lengths.
