A ceiling access panel is an opening fitted with a removable, often hinged or latchable door that allows for easy access to the space above the ceiling. This area, commonly known as the plenum, contains various building systems, including electrical wiring, HVAC ducts, plumbing lines, and fire suppression systems. Access panels serve as a vital means for maintenance personnel to reach these systems without having to undertake invasive procedures that could disrupt the integrity and appearance of the ceilings.
