FieldShield Aerial 500 Microduct is a 10 mm diameter, self supporting (figure-8 style) microduct intended to deploy fiber the same way an aerial drop is installed. Designed to comply with North American storm and ice loading standards, the 3.18 mm stranded galvanized wire strength member makes FieldShield Aerial 500 Microduct the perfect solution for spanning lengths 250 to 500 feet or lashing to an existing support strand. The FieldShield Aerial 500 Microduct supports FieldShield Pushable Optical Fiber up to 4 mm in diameter.
