In 2004, the company added a BMC marking sign product line, which consists of coated paper cards available in 3 different sizes. These signs meet posting requirements in the lawn and garden industry. A polyethylene flag was also added in 2004. Compared to vinyl, a polyethylene flag is a little more rigid and more suitable in colder climates. Blackburn Manufacturing also offers additional marking and safety products including flagging tape, barricade tape, Stake Chaser Whiskers, safety vests, traffic cones and more to better service their customers.
