Authorities continue to investigate the cause of a fire at the Shelter Products plant in New Ulm over the weekend. Fire crews from New Ulm and Courtland were called out to the facility on Front Street in New Ulm at around 4pm Saturday, and had the fire under control within an hour. Assistant New Ulm Fire Chief Aaron Wilfahrt says that the fire was in a pole barn next to the main plant, and no one was injured in the blaze. He says that the building was vacated at the time of the fire, and that pedestrians alerted the manager, who was inside the main building. The building on fire reportedly contained Shelter Products inventory such as custom doors along with company owner Duane Lambrecht’s classic car collection. Preliminary damage estimates are as high as a million dollars. Shelter Products says that the fire did not effect the business and there will be no delays in shipping or filling of orders.
