Trap Door Ceiling A Trap Door Ceiling, also known as a Ceiling Access Panel, is a discreet entry point designed to provide access to utilities such as electrical wiring, HVAC systems, and plumbing concealed within false ceilings. These access panels are essential for maintenance and inspections without disturbing the overall aesthetic of a space. Trap door ceilings are available in various materials like gypsum, metal, and fire-rated options, ensuring durability and functionality. They are widely used in commercial, residential, and industrial buildings where concealed but accessible service points are required.
