Under mount tackle box holder was developed to hold 2-3700 series Planno tackle boxes. The Under mount tackle box holder was developed to fit under my 32" x 14" table or the 40" x 16" table. All the current tables are drilled for this box holder, my older 32" & 40" Miller Marine Products rigging tables can accept this accessory but drilling and fitting will need to be done. This tackle box holder can also be used in other under mount applications for example under a box seat. Product does not include tackle boxes this is the holder you must source the boxes from another source.
