Besser is an International Company headquarters from Alpena, Michigan, and the exclusive manufacturer of LokBlok, Inc. molds. Our molds can fit in most of Besser’s machines. This allows LokBlok units to be produced by concrete block plants, anywhere in the world, with Besser machines. For example, we can take our molds to Dagostino Building Blocks Inc and have them make are LokBlok units.
