Setup and Installation
The WIN STELLAR door system is designed for straightforward assembly. The jamb kit requires assembly, and the door panel does not come with pre-drilled boreholes for door hardware, allowing for custom placement. A nailer and saw will be required for installation.
Installation Steps:
- Prepare the Rough Opening: Ensure your rough opening dimensions are appropriate for the door size (30'' x 82''-82.5'' for this model). The door slab and prehung jamb can be trimmed 0.5 inches from both the top and bottom edges if minor adjustments are needed.
- Assemble the Jamb Kit: Connect the header to the hinge jamb and strike jamb. The hinges are already screwed onto one side of the hinge jamb, simplifying this step.
- Attach Door to Jamb: The other side of the hinges is designed for easy screw attachment to the door panel. Align the door panel with the pre-attached hinges on the jamb and secure it using the provided screws. Note that the door panel does not have a pre-drilled borehole for the door handle/lock, allowing you to choose your desired hardware placement.
- Install Assembled Unit: Carefully place the assembled door and jamb unit into the rough opening. Use shims to ensure the unit is plumb, level, and square within the opening.
- Secure the Jamb: Once aligned, secure the jamb to the rough framing using appropriate fasteners (e.g., nails from a nailer).
- Finish Trim and Hardware: Install any necessary trim around the door frame. Drill the borehole for your chosen door handle and lock, then install the hardware according to its manufacturer's instructions.

Product Features
The WIN STELLAR interior door is engineered with quality materials and thoughtful design for enhanced performance and aesthetic appeal.
Solid Core MDF Construction:
The heavy-duty door slab is constructed from solid core MDF (Medium-Density Fiberboard), providing superior durability, sound dampening, and privacy compared to hollow core doors. This material is safe and sturdy, contributing to a quieter indoor environment.

Paintable Primed Finish:
The door features a prefinished surface with a three-layer painting technique, including a water-resistant coating, a primed layer for perfection, and an extra finish for enhanced smoothness and durability. This primed surface is ready for custom painting, allowing you to match your interior decor.

Durable and Environmentally Friendly:

Operating Instructions
Once installed, your WIN STELLAR interior door operates like any standard hinged door. Ensure that the door swings freely and closes securely within the jamb. The solid core construction provides a substantial feel and contributes to sound reduction when closed.
- To open, turn the door handle and pull or push the door in the direction of its swing.
- To close, gently push the door until it latches securely into the strike plate on the jamb.
- Avoid slamming the door to prevent damage to the door, frame, or hardware.
Care and Maintenance
Proper care and maintenance will help preserve the appearance and functionality of your WIN STELLAR interior door.
Cleaning:
- For general cleaning, wipe the door surface with a soft, damp cloth.
- For stubborn marks, use a mild, non-abrasive household cleaner. Avoid harsh chemicals or abrasive scrubbers, which can damage the finish.
- Dry the surface immediately after cleaning to prevent water spots.
Painting:
The door comes with a primed finish, ready for painting. Use high-quality interior paint suitable for MDF surfaces. Follow the paint manufacturer's instructions for application, drying times, and recoating.
Hardware:
Periodically check the tightness of all screws on the hinges and door hardware. Tighten as necessary to ensure smooth operation and prevent sagging.
Troubleshooting
If you encounter issues with your door, consider the following common solutions:
- Door Does Not Close Properly:
- Check if the door frame is plumb and square. Adjust shims if needed.
- Ensure hinges are securely fastened to both the door and the jamb.
- Verify the strike plate alignment with the door latch. Adjust the strike plate if necessary.
- Door Squeaks:
- Apply a small amount of lubricant (e.g., silicone spray or petroleum jelly) to the hinge pins.
- Paint Adhesion Issues:
- Ensure the door surface was clean and dry before painting.
- Use a high-quality primer if the existing primed surface was compromised or if you are using a paint type that requires additional priming.
