Materials & Construction
Wayne Dalton's 2411 features nominal 24-gauge ribbed steel sections with vertical stiles attached to the interior. These 20-gauge stiles are securely attached with No. 8 screws and adhesive and have pre-located, extruded holes for hinge attachment. The exterior ribbing consists of two deep and four shallow ribs in each section, making it ideal for moderate use. The bottom section features a vinyl bulb-shaped astragal, held by a roll-formed, hot-dipped galvanized steel retainer.
Additional options include top head seal, joint seals and jamb seals. Optional insulation, consisting of 1 9/16" expanded polystyrene and covered with .015" minimum embossed pre-painted white steel provides an R-value of up to 7.64 and a U-value as low as 0.13. Lite options include insulated or non-insulated factory-installed vision lites or aluminum full-view sections for maximum visibility.
