Wax Tube Fastener is ideal for securing foundation into grooved top bar (cut comb and chunk honey) frames. Metal cylinder is filled by lowering into container of hot, liquid beeswax. When cylinder is filled, wax is retained in cylinder by placing over air hole. With foundation in place, the wax tube fastener is run along the top bar groove. By removing finger from air hole, a small amount of wax flows out to cement the foundation to the top bar.
