Rolling steel door model 610 is a perennial best-seller for good reason. The standard features exceed the norm for quality and a myriad of options allow for true customization. The Model 610 is built with a standard galvanized steel curtain, or an optional stainless steel or aluminum curtain. The standard curtain slat is the attractive C-187 curved profile, with additional slat options available in curved and flat. Finishes range from four standard colors to approximately 200 powder coat colors or matched to your specification. A host of other options — including motor operation, pass doors, exhaust ports, between-jambs mounting, cylinder locks and special usage packages — allow the 610 to be adapted to any environment.
