Blum is an American company that produces speciality hardware such as drawer organisers and runners, door lift systems and concealed hinges. When installed on your cabinetry, the Blum hinge is completely hidden from view when the cabinet door is closed. The Blum hinge has a spring-loaded mechanism that keeps your cabinet or cupboard door closed without the installation of a separate door catch. Installation and adjustment of your Blum hinges should take approximately one hour per door.
Determine the location of your hinge on the back of the cabinet door. Place a square along the hinged edge of door and mark a line approximately 2 inches long to indicate the centre line of the hinge to be installed. Hold the door to the cabinet and transfer the centre line to the inside of the cabinet wall approximately 2 inches.
Install a 1 3/8-inch diameter Forstner bit into a power drill. Drill a hole ½-inch deep in the cabinet door surface using the mark you made in step 1, making sure the edge of the hole is 1/16-inch to ¼-inch away from the edge of the door.
Press the hinge cup into the hole you have drilled with the arm of the hinge facing outward from the edge of the door. Secure the cup into place with the screws provided and a Phillips screwdriver.
Hold the hinge clip to the cabinet wall, centring it on the line you marked in step 1. Make sure the clip is set back from the front edge of the cabinet by a distance equal to the thickness of the cabinet door. Mount the clip with the screws provided with a Phillips screwdriver.
Repeat steps 1 through 4 for additional hinges. Mount the door to the cabinet by first opening the hinges, or making sure the hinge arm on the cabinet door is sticking straight out. Hold the door to the cabinet and press the arm of each hinge to the hinge clip until they snap into place.
Test the operation of the door. Adjust the hinges if the door rubs by turning the adjustment screws on the inside of the hinge and hinge clip with a Phillips screwdriver.
The amount of the edge of the cabinet door that is exposed when it is closed is determined by how far back you drill the 1 3/8-inch mounting hole from the edge of the cabinet door. Mount your hinge in a scrap piece of wood and mount it to the cabinet using the above instructions; this way you can determine where the mounting hole for the hinge should be before actually drilling the cabinet door.
