Four Hinges × Modular Pivot Core
One Platform System
Multifunctional Modular Self-Closing Door Hinge · D · K · M · R × HSW · TSW · LSW
D · K · M · R share a modular pivot-core architecture; the DM catalog highlights HSW / TSW / LSW as the three function sets, with S stored torque and W concealed wiring shown across the catalog models — integrating self-closing, damped braking, safety pin protection and emergency escape — engineered for the world's doors.

Multifunctional Double Expansion Anchor
Patent pending at the Taiwan IP Office (CP-39498)
When used with D / K / M / R hinges, no special washer is needed — it locks directly into the three grooves on the leaf. Just one 5 mm hex wrench for the full installation: fast, safe, and precise, greatly cutting labor and cost. The floating spindle auto-matches brake force to the stored torque — simply turn clockwise until the door closes automatically and the setup is done.

＊ 4 series × 3 modules = 12 models. In each code, S is the shared stored-torque mechanism and W is the concealed-wiring version. The D series shows the A-type dual-stage gear (+) flagship core; K / M / R share the modular pivot platform, with A / B core configuration confirmed per project spec. See each series page for full specs and installation.
