The CDC-4800 TA Concealed Door Closer with Hold Open is a premium architectural door control solution designed to deliver smooth, quiet, and reliable door operation while maintaining a clean, minimalist appearance. Installed discreetly within the door and frame, it provides superior aesthetics without the visual impact of conventional surface-mounted door closers.
Engineered with a precision rack and pinion mechanism and fully hydraulic control, the CDC-4800 TA ensures consistent performance and long-lasting durability. The adjustable closing force (EN 2–4) allows the closer to accommodate a variety of door sizes and weights, while independently adjustable closing and latching speeds provide precise control for enhanced safety and user comfort.
The integrated concealed hold-open track arm allows the door to remain open when required, making it ideal for high-traffic environments. Power adjustment is easily accessible from the top using Allen keys, simplifying installation and fine-tuning. Its non-handed design is suitable for both left- and right-oriented doors, offering maximum installation flexibility.
Tested for 500,000 operating cycles, the CDC-4800 TA is built for dependable performance in demanding residential and commercial applications.
