Wayne Dalton – Model 900 Rolling Steel Service Door

Wayne Dalton – Model 900 Rolling Steel Service Door

Rolling Service Door

Wayne Dalton’s Model 900 Rolling Service Door is ideal for jobs where an economical solution, as well as durability and strength are needed. This door offers flexibility in curtain materials with choices of galvanized steel, stainless steel, or aluminum.

Our Model 900 rolling service doors are composed of curved or flat-faced slats that provide a natural watershed, helping to reduce corrosion. The slats are designed with free-acting interlocking joints that permit easy articulation when the door coils.

Model 900 features a strong double-angle bottom bar designed for easy installation and does not require fasteners in the guide openings, so the bottom bar does not interfere with door operation.

The 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.)
