The bottom of the window glass fits into a component called the sash channel. The sash channel serves as a guiding structure in which the glass window is positioned and held securely in place. It is an integral part of a window assembly, allowing for smooth operation of the window movement, especially in vehicles where the window may be raised or lowered. The sash channel provides support and ensures that the glass is aligned properly, minimizing the chances of rattling or misalignment during operation. Understanding the role of the sash channel is essential for appraisers evaluating the condition and functionality of vehicle windows.

In contrast, the run channel pertains to the area where the window glass slides within the door or frame, while the window regulator is responsible for the mechanism that moves the glass up or down. The edge guard typically refers to a protective feature that helps seal or finish the edges, but it does not directly hold the window glass in place.
