The Fortress is a lineset covering system for mini-splits or ducted split air conditioning systems. It is constructed of strong, extruded PVC lengths and injection-molded fittings that are highly UV- and weather-resistant. The cover system is made specifically for the U.S. market with full 8-foot lengths to reduce joints and waste with two deep profiles - 3.5 inches for standard linesets and 4.5 inches for heavily-insulated or multiple linesets. Four colors of white, ivory, brown, and gray coordinate with most condenser and home exterior colors. It can be used for temperatures in the range of -4° to 140°F. Specially designed sweep elbows accommodate long radius 90-degree bends. Two adjustable lineset retainer clips are included with each duct length. An extensive range of 16 fittings accommodates any application, says the manufacturer. Stainless steel screws eliminate rust marks.
