This Canadian made inner cover will fit the standard 4 frame nuc boxes. It comes assembled with the 2″ hole in the center and has a deeper overhang so you do not crush as many bees when putting this lid on your hive!

This item is part of the stackable 4 frame nucs collection. These 4 frame products are intended to allow for stacking on each other, as well as stacking with standard 10-frame Langstroth equipment. The nuc boxes in this collection are sized so that 2x side-by-side boxes have the same dimensions as 1x 10-frame box.
