Blum is a preeminent manufacturer of European-style cabinet hinges---two-part hinges that hold the cabinet door to the cabinet from the inside. You cannot see these hinges once you close the cabinet door. Cabinetmakers install Blum hinges on face-frame as well as frameless cabinets. Designers use hidden hinges to present a streamlined view of the cabinetry surface, uninterrupted by bulky hinge hardware. You may unclip the two parts of a Blum hinge if you need to remove your cabinet door.
Measure over from the edge of the door 7/8 inch (22.5mm) on a frameless cabinet. Measure 5 1/64 inches (20.5mm) for face-frame cabinets. Mark the centre of the hinge cup location with a pencil.
Drill a flat-bottomed hole 1 3/8-inch (35mm) in diameter on the interior-facing side of the cabinet door to a depth of 1/2 inch using a Forstner-type bit.
Hold the hinge so that its arm is perpendicular to the edge of the door and extends toward the carcase of the cabinet. Place the circular cup portion so that it rests in the hole you created.
Screw the hinge into place in the door using two screws and the hinge as a template.
Position the mounting plate on the carcase of the cabinet so that the holes are 1 15/32 inches (37mm) from the front edge of the cabinet. Locate the hinge mounting plate on the frame for face-frame cabinets and screw the mounting plate into place.
Connect the arm of the hinge onto the mounting plate by clipping it into place.
Some carpentry or cabinetry shops have a special Blum mini-press and they may agree to bore the holes for you with the press, possibly for a fee.
Adjust the measurements to suit your project to account for variations in hinge and cabinet sizes.
