Installation Steps

1. Prepare Tools and Materials: Gather necessary tools including drill, screwdriver, measuring tape, pencil, and appropriate screws. Ensure you have the correct number of hinges for your door size (typically 3 hinges per standard door).
2. Mark Hinge Positions: Measure and mark hinge locations on both door and frame. For optimal support, position hinges 7 inches from the top, 11 inches from the bottom, and centered between these two points.
3. Attach Hinge Plates: Align hinge plates with your marks, pre-drill pilot holes to prevent wood splitting, then secure with screws. Ensure plates are flush with door and frame surfaces.
4. Connect Door to Frame: With assistance, align hinge knuckles and insert hinge pins. Test door movement to ensure smooth operation without binding or excessive play.
5. Final Adjustments: Check door alignment and make any necessary adjustments. Ensure the door closes properly and maintains the required fire rating when paired with appropriate door seals.
