Operating Instructions
Follow these steps for safe and efficient door installation using the Saker Door Panel Installation Kit:
- Prepare the Door: Ensure the door is clean and free of debris.
- Position the Dollies: Place one dolly unit on each side of the bottom edge of the door. Ensure the non-slip mats are in contact with the door surface.
- Adjust Thickness: Loosen the thickness adjustment knobs. Slide the dolly units to firmly grip the door, accommodating its thickness (0.8 to 2.36 inches). Tighten the knobs securely.
- Adjust Height: Use the height adjustment screws to raise or lower the door to the desired installation height. Ensure the door is level.
- Lock Wheels (Optional for Static Work): If the door needs to remain stationary during adjustments or initial fitting, engage the locking mechanisms on the wheels for added stability.
- Transport the Door: Unlock the wheels and carefully roll the door to the installation location. The 360-degree swivel wheels allow for easy maneuverability.
- Final Positioning: Once at the installation point, fine-tune the height and position as needed. Engage wheel locks if required for stability during hinge or frame attachment.
- Install the Door: Proceed with the door installation process (e.g., attaching hinges, securing to frame).
- Remove Dollies: Once the door is securely installed, loosen the thickness and height adjustments, and carefully remove the dolly units.
