The purpose of a hanger cover in door installations is to?

The purpose of a hanger cover in door installations primarily revolves around preventing dirt accumulation. A hanger cover serves as a protective barrier that shields the internal components of the door system, including the hangers and rollers, from dust, debris, and grime. This is crucial for maintaining the smooth operation of the door over time and ensuring durability. A clean operating environment for these components helps reduce wear and tear, which could lead to malfunction or increased maintenance needs. By keeping contaminants out, a hanger cover contributes significantly to the longevity and reliability of the door system.

While aesthetic appeal and frame strength are important considerations in installations, they do not specifically define the role of a hanger cover. Similarly, while the cover could indirectly support the door's function by keeping the mechanics clean, it is not primarily intended to support the door's weight.
