RectorSeal Fortress 84105 4.5" White Line Set Cover Kit - 12 Ft Professional HVAC Wall Duct System

The RectorSeal Fortress 84105 Line Set Cover Kit is a premium HVAC line hide solution designed to protect and conceal exposed refrigerant lines, drain tubing, communication wiring, and electrical cables. Engineered for mini split systems, heat pumps, condensers, and conventional air conditioning installations, Fortress is trusted by HVAC professionals who demand a cleaner appearance, superior durability, and long-lasting outdoor performance.

Unlike economy line set covers, Fortress features heavy-duty UV-stabilized, fire-resistant PVC construction and longer duct sections that reduce joints and create a more professional finished appearance.
