Concealed Door Closer for Modern Interiors

The biggest advantage of the Ozone CDC 3800E concealed door closer is its discreet installation. Unlike conventional surface-mounted door closers, the mechanism is concealed within the door and frame, helping preserve the clean appearance of the entrance.

With no bulky surface-mounted body or conventional visible arm dominating the door, the concealed hydraulic door closer is particularly suited to contemporary homes, offices, hotels, commercial spaces and architectural projects.

Smooth Hydraulic Door Closing

The CDC 3800E uses a hydraulic door-closing mechanism combined with a rack and pinion system to provide controlled door movement.

Its dual-speed hydraulic adjustment allows the closing and latching phases to be controlled independently. This helps prevent sudden door slamming while allowing the door to close and latch smoothly.

The result is a more controlled and comfortable door-closing experience while reducing unnecessary impact on the door and frame.

EN 3 Concealed Door Closer for Doors up to 60 kg

The Ozone CDC 3800E is designed according to EN 3 specifications and supports doors weighing up to 60 kg, with a maximum door width of 950 mm.

Durable & Long-Lasting Door Closer

The CDC 3800E is designed for repeated use and has been cycle-tested for up to 5,00,000 operations. Its robust hydraulic mechanism is intended to provide consistent door-closing performance over extended use.

This makes the Ozone concealed door closer suitable for applications where dependable operation and long-term durability are important.
