W-Tec 3D Concealed Door Hinge

W-Tec concealed door hinges are designed to mount flush fit to doors with no hinge element (knuckle) showing when the door in a closed position. Suitable for all door leaf thicknesses.

Manufactured from steel and Zamak. Has a unique kinematic mechanism where the door weight is transferred through three independent levers and is sustained in seven independent axis. This innovative design minimizes door sag over the lifetime of the application as the product will still function should two thirds of the levers fail due to the axis design.
