APPLICATIONS · REAL DOOR SCENES
Every model maps
to a real door scene.
The D · K · M · R hinge series covers three application themes: Glass Door Hinge System, MDEA double-expansion anchoring, and W concealed wiring. All 12 models map to real-world scenarios — hotel suites, glass office partitions, healthcare, lightweight bathroom doors, smart access control, server rooms, residential entries and corner shower doors.
Any door can use any of D, K, M, or R — the difference is leaf geometry and the mounting space it needs: D/K are parallel, flush wall-to-door mounts (flagship and universal); M needs a flat, flush 180° door-to-wall plane; R's offset leaf is built for 90°/45° corners and space-constrained installs.
Available with UL-10362 Teflon 250°C or UL-1569 PVC 105°C 12-color flat cable, compatible with ASSA ABLOY industry standards.

Bathroom Corner Shower Door
Compact wet/dry bathrooms often meet the wall at a 90° or 45° corner with limited depth behind — exactly where the R series' offset barrel leaf excels; the mechanical brake with safety pin holds the door reliably and closes it steadily.
