Install Wood Supports
NOTICE: For proper countertop installation, the top of the sink
must not extend above the top edge of the cabinet.
Cut two lengths of support framing to extend along the inside
walls on each side of the base cabinet.
Measure and mark the support mounting locations; ensuring the
sink rim will sit at, or slightly below the top edge of the cabinet.
Position and level the supports.
Secure the supports with construction adhesive and screws (not
provided).
Cut four lengths of support framing to extend from the bottom of
the installed supports to the floor of the cabinet.
Secure the vertical supports with construction adhesive and
screws (not provided).
