In recent years, while the size of residential spaces has been shrinking, there has been a growing demand from architects and designers for designs that "reduce lines as much as possible." However, designing spaces to appear clean and spacious by making door heights reach the ceiling or by minimizing the visibility of frames has posed challenges that require high skill levels from carpenters and significant construction time when attempted with conventional on-site construction methods. Against this backdrop, this year's Dretas has developed doors and storage fixtures that do not reveal frames, with the concept of "creating a noise-free space with empty space." ■ Base Frame (Fixtures) The structure hides the frame within the wall, achieving a refined design without the frame being visible from either side. It features a specially designed frame and concealed hinges that allow for 180-degree opening and closing. Frame widths (132mm, 147mm, 183mm) are set to accommodate wall thickness, eliminating the need for frame processing and supporting smooth installation. ■ Outset Frame (Storage Fixtures) The structure has the frame attached to the inside of the door, allowing the door and wall to fit flatly together. It can be configured for two or three panels, seamlessly blending even large wall storage into the space as if it were "just a wall." By using additional elements like the 3mm thick "Baseboard S-type," the installation becomes even more beautiful, enhancing the noise-free space.

The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who want to enter, whether on a busy street or in a narrow passageway. The automatic door opens simply by bringing your hand close, addressing hygiene concerns even in facilities used by a large number of people. Depending on the application and installation location, you can choose between "Non-vision Mount Type/HA-T401" and "Non-vision Built-in Type/HA-T520." 【Recommended for such places!】 ☑ Entrance facing a busy passageway ☑ Presence of counters or signs near the door ☑ Buildings facing narrow passageways ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors 【Features】 ● Adaptable to various door types with four detection spot settings ● Reduces unnecessary opening and closing to minimize power consumption, contributing to energy-saving effects ● Equipped with a light touch function, allowing the door to open and close simply by waving your hand, ensuring hygiene ● Can also be used as a wide detection range non-vision infrared sensor ◎ For more details, please download the materials or contact us.
