Stealth Ceiling/Drop-in Access Panels (18in x 18in Access Opening) from Wind-lock® are designed to be an attractive alternative to typical access panels in commercial and residential buildings. Their glass-fiber-reinforced-gypsum (GFRG) based construction can’t rust and blends seamlessly with new or retrofitted drywall ceilings and walls. The design of the stealth access panel ensures that your aesthetic style is noticed and not your access panels.
