14x16inch/35x40cm Waterproof Access Door designed for durable, lowprofile access and noise reduction Key benefits Provides a sturdy, waterproof access point for ceilings and walls where regular maintenance or concealed routing is required. Reduces noise transmission through its aluminum alloy honeycomb core, improving acoustic comfort in living and working spaces. Installs without nails or screws into framing, allowing quick, secure fitting and neat finished appearance that can be painted to match surroundings. Materials and construction Frame: 2 mm 0.07 in thick ABS for impact resistance and dimensional stability. Panel: 7 mm 0.28 in thick aluminum alloy honeycomb panel that combines rigidity, light weight, and sound dampening. Overall build is designed to withstand humid or damp environments such as bathrooms, kitchens, and basements. Performance and functions Waterproof construction helps prevent moisture damage in wet locations while keeping the access point functional for routine inspections and repairs. Honeycomb structure modifies air circulation and slows sound propagation to effectively reduce transmitted noise from mechanical equipment or adjacent rooms. Durable materials resist everyday wear and tear for reliable long term use.
