Wax foundation used by modern beekeepers to give bees a uniform guide to build the comb in turn helping increase honey production. Wire embedding makes foundation stronger and allows for centrifuge extraction. Wax foundations are made in various sizes, depending on the frame they will be inserted into. The Langstroth wired and unwired deep foundation fits Langstroth Hoffman brood and jumbo frames (LAN70, LAN73). All foundation packs are available as wired or unwired in packs of 10 sheets.
