Product Overview

The GU VTS 634 concealed door closer is engineered for single-leaf doors, featuring a hidden installation inside the door leaf and a sliding rail mounted in the frame. It offers seamless integration in commercial and institutional projects where aesthetic preference dictates minimal visible hardware. Certified to EN 1154 and compliant with DIN 18040 for barrier-free construction, it is suitable for environments requiring both accessibility and reliable door closing, accommodating door leaf widths up to 1100 mm and opening angles up to 120 degrees.

The standout feature of the GU VTS 634 is its cam technology, which facilitates easy door opening and supports barrier-free access as required by DIN 18040. This eliminates operating force concerns during installation and inspection in accessible building projects, streamlining compliance for architects and contractors. Recommended for barrier-free applications in healthcare, education, public institutions, and hospitality, especially where invisible hardware is preferred.
