The Wayne Dalton Model 800 is a Rolling Service Door 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.
Wayne Dalton composes Model 800 doors of curved or flat-faced slats that provide a natural water-shed. Slats are designed with free-acting interlocking joints that permit easy articulation when the door coils.
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 comprises a spring barrel that 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 inches per lineal foot of span.)
