Mini-Boards are attachments that sit on the grate and lock into place into the grate squares. This provides a flat surface for cutting or carving and is ideal for rib bones removal for those that use electric knives or filleting methods that remove the rib bones in a second cut. Also used for rig changing surface or bait cutting while in a boat. Stands alone or for use on the grate. Surrounding gutter holds mess or small dropped rigging items.
