1. Install 4 BUNK SOCKET BRACKETS and PLATES on
front and rear CRADLES using Step 5 Bolt Package. Each
BUNK SOCKET Assembly uses:
4 - 3/8 x 2-1/2" hex bolts
4 - 3/8 nylon locknuts
PLATES should be placed on the outside of the CRADLE
and the BRACKETS on the inside. Leave bolts loose to
allow for adjustment.
Place a BUNK DOWN LEG in each BUNK SOCKET
BRACKET and hold in place using:
1 - 3/8 x 2-1/2" clevis pin
1 - hairpin cotter
Determine proper location for BUNKS making sure
they are equal distance from the center of the cradle.
The simplest way to determine this is by measuring the
distance between the two inside bunks on your boat
trailer. If you do not have a trailer start with each bunk
16" from the center of the cradle (32" apart), or measure
to the at n on the bottom of the hull closest to the
16” mark. Slide the BUNK SOCKETS into position and
tighten all bolts.
If you are using the bunks for a Pontoon:
Measure the distance between the rib on the bottom of
each toon or log. Divide that measurement in half to get
the distance from the middle of the cradle to the center
of each bunk set. Each pair of bunks should be approxi-
mately 6” apart.
2. Adjust BUNK U CHANNEL on underside of each BUNK
to match BUNK DOWN LEGS and tighten 3/8 hex nut to
hold rmly in place. Do not overtighten!
Place BUNKS on top of BUNK DOWN LEGS and bolt in
place using:
4 - 1/2 x 3" hex bolts
4 - 1/2 nylon locknut
While holding BUNK at snug bolt so bunk will still
pivot under the load of the boat. This will insure that
the bunks will conform to your boat. Load boat onto
lift making sure that the weight is balanced between
the two CRADLES. Check and reposition bunks as
necessary.
WARNING : NEVER ADJUST BUNKS WHILE BOAT IS
ON LIFT.
