Built here in our Oregon woodshop, this telescoping cover is best in class. We use a full 2” frame, a 3/8” exterior grade panel, and a heavy gauge rust-proof metal cover that is more robust then the soft aluminum that most manufacturers use. This metal cover wraps around the wood a full 1” to provide outstanding protection. Our wood frame is rabbet jointed, glued and stapled for great strength. The panel is also glued and stapled to the frame.
Our insulated telescoping cover option has a liner of corrugated insulation sandwiched between the metal cover and the ply panel to increase thermal isolation of the hive. This creates channeled air pockets that help hive temperature regulation year round.
