Check the listing for details. Pine Migratory Top Cover or Lid for 10 Frame Hive Beekeeping. Condition: New. Listed at 38.00 USD. Pine Migratory Top Cover or LidWhat is it?Originally large-scale and commercial beekeepers needed them to place large number of beehives on trucks or trailers to move them around. Today more and more beekeepers are using them for the following reasons:You no longer need an inner cover so less equipment to keep aroundThey are flush to the sides, so they take up less spaceThey cost less and you save money by not having unnecessary parts (Inner Covers) and you save in labor costs by not having to handle extra partsEasy to drill a hole and install external feeders which are accessible by the bees only from the interior of the hiveShims on the underside gives enough space for pollen patty’sLess space for hive beetles to hide. How is it constructed?Rough cut Pine is planed down to a perfect ¾" thicknessBoards are cut and squared to dimensions below.Most migratory cover bases are made with plywood or planks pressed together. The base for this cover is made with tongue and groove Pine planks glued and clamped together.The end cleats are 2½” wide and secured to the base with a ⅜” deep dado, glue, and external screwsThe crossbar supports are 1¾” wide and secured to the base with glue and external screwsMigratory covers sit directly on top of your hive with no inner cover which means there is inadequate bee space below the cover. We added a ¼” rim along the underside of the cover to allow enough space for the bees and pollen patties.
