Plenum Innerduct

Plenum innerduct is used in indoor environments where strict fire and smoke requirements apply, such as air handling spaces, risers, and commercial building infrastructure. Manufactured from PVDF (polyvinylidene fluoride), it meets the most stringent flame and smoke standards while providing a flexible pathway for fiber and communications cables. Galloway stocks plenum innerduct in the sizes and configurations required for indoor cable management across data centers, commercial buildings, and multi-dwelling units.
