Chief MAC501B Flat Panel In-Wall Mount

Upgrade your home theater or office display with the Chief MAC501B Flat Panel In-Wall Mount, a premium mounting solution engineered to vanish a swing-arm installation inside the wall. This design transforms bulky, exposed hardware into a sleek, no-profile footprint that blends with any decor while maintaining reliable, tool-free adjustability. Ideal for 40-inch displays, this mount leverages Chief’s modular mounting system to streamline installation, simplify future upgrades, and deliver precise alignment with minimal effort. By concealing the arm within the wall, the MAC501B reduces cable clutter, improves ventilation around the display, and creates a theater-like aesthetic that keeps the focus on the screen. The system is designed for quick, accurate mounting and straightforward service, offering predictable performance across various environments including living rooms, classrooms, and conference spaces. The MAC501B integrates with Chief's mounting ecosystem, enabling scalable setups that can adapt as your display needs evolve without replacing the core hardware. The low-profile approach not only enhances interior design but also minimizes protrusions, helping maintain safe, clean sightlines in busy areas, while preserving easy access to ports and connections through thoughtfully placed access points. With a focus on long-term reliability, the MAC501B supports routine adjustments and occasional upgrades while maintaining alignment and load-bearing capability.

• In-wall concealment and ultra-low-profile design: The MAC501B hides the entire swing-arm mounting system inside the wall, eliminating bulky brackets and protruding hardware. This feature delivers a near-zero footprint, letting the display breathe against the wall and preserving sightlines and room aesthetics. The in-wall approach is especially advantageous in multi-purpose spaces, glass-walled offices, and living rooms where clean, modern lines are essential. Enjoy a seamless look that keeps attention on the screen rather than the mount.
• Sturdy 75 lb weight capacity for reliable performance: Designed to support up to 75 pounds, the MAC501B provides confidence that your 40-inch display will sit securely on a concealed mounting system. This capacity accommodates a wide range of LED, LCD, and other common displays found in residential, commercial, and educational settings. You can upgrade to a larger screen or adjust the configuration over time without needing a new mounting solution, ensuring long-term compatibility and fewer upgrades.
• Modular mounting system with adjustable connectors for quick repositioning: The MAC501B employs Chief’s modular connectors that enable fast, on-wall adjustments without disassembly. Whether you’re aligning multiple displays, adapting to a new layout, or rerouting cables, the modular approach makes changes straightforward. This flexibility minimizes downtime during installations and service events, helping technicians achieve precise alignment quickly and consistently across rooms or builds.
• Easy, tool-friendly adjustments and precise alignment: With the wall concealed and connectors designed for smooth motion, fine-tuning tilt-free leveling and horizontal alignment becomes a simple, repeatable process. The high-quality hardware ensures smooth operation with minimal play, so you’ll enjoy uniform gaps and tight seams along the screen edge. This ease-of-use is essential for achieving a professional, cinema-like display experience in home theaters, conference rooms, and digital signage environments.
• Durable construction and a professional-grade installation solution: The MAC501B is built to endure the demands of frequent rearrangements and long-term use. By placing the mounting hardware behind the wall, it protects critical components from accidental bumps and reduces exposure to dust and debris. The design aligns with commercial-grade standards, giving installers peace of mind that the system will maintain alignment and support for years to come, all while delivering a clean, unobtrusive look.
