Upon authorization, the barricade, bollard or barrier lowers to let the vehicle pass. Delta Scientific Corporation is headquartered in Palmdale, where it has production facilities covering more than 260,000 square feet of building space. PALMDALE – Delta Scientific says the U.S. Courthouse in Syracuse, New York, will get the 255th Delta counterterrorist-barricade system to protect a federal courthouse or associated building. The Department of Justice has been purchasing Delta’s barricade systems over the past 18 years, and 103 are in place. “The Department of Justice has done a good job of securing their critical facilities,” said David Dickinson, Delta Scientific senior vice president. “They have used 32 different barricade models out of over 50 Delta Scientific options.” Delta vehicle barricades control the entrances and exits of buildings, keeping unauthorized vehicles from parking too close to a structure or in subterranean garages where explosives can have a devastating effect.
