The Wayne Dalton Model 800 Rolling Service Door is designed to meet the tough requirements of virtually any commercial or industrial application. Model 800 offers flexibility in substrate materials with choices of galvanized or prime steel, stainless steel, or aluminum.

Our Model 800 rolling service door is composed of curved or flat-faced slats that provide a natural water-shed, helping to reduce corrosion. The slats are designed with free-acting interlocking joints that permit easy articulation when the door coils.

Rolling Service Door Model 800 features a strong double-angle bottom bar designed for easy installation and does not require fasteners protruding into the guide openings, so the bottom bar does not interfere with door operation.

Counterbalance assembly consists of a spring barrel which serves as a load-carrying beam. It encases the counterbalance mechanism and provides the axis around which the curtain coils. (Deflection is limited to 0.033" per lineal foot of span.)
