Is used where there is limited requirement
for rake change between light and heavy airs.
Used in conjuction with the A4772DR-KIT (not
suplied) heavy- duty vernier adjuster with captive de-raker. Made from
heavy-duty 14 gauge 316 stainless steel, it easily handles higher loads
and with the aid of calibrated settings, fast pins and captive de-raker,
the result is easy fine-tuning on the water.
