Pre-Installation Preparation: First, verify the dimensions, flatness, and clearance between door panel and frame. Count the required quantity of black flush door hinges and matching screws. Prepare basic tools including Phillips screwdriver, pencil, and measuring tape.

Positioning and Fixing: Place the door panel correctly within the frame. Unfold the hinge, positioning both leaves flush against the door panel side and frame interior respectively. Find the optimal position and mark screw holes with a pencil. Use a screwdriver to secure the hinge preliminarily by screwing into each pre-marked hole.
