This 6-piece magnetic door hinge jig set helps position cabinet hinges for drilling, screw placement, and door fitting. The built-in guide supports a consistent 2 mm door gap and 90-degree alignment. Its magnetic backing holds each jig on compatible metal plates to help reduce movement during setup. Suitable for cabinet installation, door replacement, furniture assembly, woodworking, renovation, and repair. Place the jig on the cabinet frame, confirm the position, then mark or drill as required. Store the compact pieces in a toolbox, drawer, or carry case. Check hinge style, workpiece dimensions, and magnetic compatibility before use.
