This unique tool allows you to drip wax along the joint to embed wax starter strips into frames, makes a really messy job easy and clean. The metal cylinder is filled by lowering into container of hot, liquid beeswax. When cylinder is filled, wax is retained in cylinder by placing finger 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.
