Pop-Out Access Panel
Overview
Our GFRG SEAMLESS™ Pop-out Access Panels are designed to provide hidden, discreet access points that blend seamlessly into the surrounding substrate.
With a smart design that includes deeper tapered edges, level 5 finish, and pre-countersunk locations, our panels provide superior strength while maintaining a stealthy integration that contractors and designers prefer.
Perfect for drywall installations, electrical, and plumbing access. Whether you’re working on new construction or retrofitting an existing building, these gypsum access doors provide a seamless solution that blends flawlessly with drywall, ensuring a clean, professional result.
Product Features
- Stealth Integration: The access panel blends seamlessly with drywall, offering a hidden appearance with minimal visible lines.
- Sustainable Design: Made from durable glass fiber reinforced gypsum (GFRG) and 70% post-consumer recycled glass for a sustainable and eco-friendly solution.
- Durable and Lightweight: Incredibly lightweight, making installations quicker and less labor-intensive.
- Easy Installation and Easy to Fit: Install with ease using coarse-thread drywall screws into pre-countersunk locations for a smooth, invisible finish.
