with the underside of the sink ledge. Determine exact loca-

tion where mounting bracket will be installed. Mark on

starter holes where marked using a 3/32” drill bit.

*Note: Depending upon fabrication of countertop, top of

mounting bracket may need to be no

tched into top of

cabinet frame.

not recommended on sinks with a left or right

dimension of 36" (914mm) or greater, or sinks with shapes

that do not allow the kit to have sufficient contact.
