Telescoping Covers are the roof of your hive. Like your own house; you want one that will withstand the harshest conditions. The top is covered with heavy duty aluminum and it telescopes down over the top of the hive to keep out the elements. Use our Inner Cover in conjunction with our Telescoping Cover to allow moisture to escape and provide proper ventilation for your colony. Please note that if you choose to purchase a Painted Telescoping Cover with an Inner Cover, the inner cover is not and should not be painted so that it can help maintain the moisture levels.
