Install New Gasket and Glass Panel

What happens here

The creator demonstrates the crucial step of installing the three rubber retainers onto the new glass panel before placing the panel into the door frame. He then carefully aligns the new glass panel into the door frame, pressing the rubber gasket firmly into place to ensure it is properly seated and stretched. He proceeds to push the new retainers into their respective slots by hand, ensuring the glass is flush with the frame but not directly touching the metal. He highlights the need for careful handling to avoid accidental breakage during this process.

Goal: Securely fit the new glass panel into the door frame using the rubber gasket and retainers.
