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. The clean white finish blends seamlessly with most residential and commercial exteriors while helping protect critical HVAC components from weather, UV exposure, and physical damage.

When appearance, durability, and long-term performance matter, HVAC professionals choose Fortress. It's the premium line set cover system designed to finish the job right the first time.

Pretty Colors to Encourage Me to Walk!
Size: X-Large, Color: (601) Bittersweet Pink / Stone / Stone
Hum. Extra large does not seem extra large. I have a slender but size 10-10.5 foot. Will keep but was hoping for a looser fit. Bought to match an Under Armour walking outfit.
