Beall Treen Mandrel Expanders Set

We now offer an expansion kit for our popular 1-1/4" Treen Mandrel which allows you to turn 1-½" or 2" ID boxes. The 1-½" expander consists of two brass rings which slide over the original mandrel. The larger expander comprises 2" diameter steel rings which fit over the mandrel, where they are secured with set screws, and a 2" aluminum gauge ring to permit easy matching of box and lid diameters
