Anyone who visits us in Oklahoma quickly discovers a consistent fact of life in our great state: it is windy. Combine this wind with a few dry years and the result is a nice dust storm. This was the situation in the 1920s when L.A. Macklanburg built his first form of weatherstrip in order to keep the dust from coming under his front door. He then built a brass-folding hand-crank weatherstrip machine and took his product to the Oklahoma State Fair in early July, 1920 and thus a new entity was born.
Led by majority share-holder Loren Plotkin's staff, the M-D team has continued to forge forward with a renewed vigor as the leader in energy efficiency products, floor trims, floor installation tools, digital level technology and quality standards for our OEM customers.
