Stormtite™ 620

These rolling steel doors are an ideal choice for keeping climate-controlled air in and the elements out. Like the Model 610, the Stormtite™ 620 offers the option of a steel, stainless steel or aluminum curtain in an array of finishes and colors. For enhanced thermal efficiency, the 620 is furnished with flat slat profiles only, as well as weatherstripping on the exterior side of the guides, on the bottom bar and a hood baffle. Additional weatherseals are available as options on the interior side of the guides and hood lintel.
