Setup and Installation
This WINSTELLAR door slab arrives pre-assembled and triple-primed, simplifying the installation process. It is ready for immediate installation and painting. This section outlines general steps; specific hardware (e.g., hinges, tracks, jambs) will have their own installation instructions that must be followed in conjunction with these guidelines.
Tools and Materials (Not Included):
- Measuring tape
- Level
- Drill and appropriate drill bits
- Screwdriver
- Hinges, door handle/knob, and latch mechanism (for hinged doors)
- Door frame (jamb) if not already installed
- Shims
- Safety glasses and gloves
General Installation Steps:
- Prepare the Opening: Ensure your door opening (with jamb installed) measures approximately 36-1/4 inches wide by 80-1/2 inches high for this 36x80 door slab. The rough opening (before jamb installation) should be approximately 38 inches wide by 82 inches high. Verify the opening is plumb, level, and square.
- Inspect the Door Slab: Before installation, carefully inspect the door slab for any damage. The door is securely packaged with a reinforced outside frame to prevent transit damage.
- Determine Door Type: This door slab is versatile and can be used for prehung, pocket, French, or barn door applications. The specific hardware and frame required will vary based on your chosen application. Refer to the instructions provided with your chosen hardware kit.
- Hardware Installation (e.g., Hinges, Handle):
- For hinged doors, mark and mortise hinge locations on both the door slab and the door jamb according to your hinge manufacturer's instructions.
- Drill holes for the door handle/knob and latch mechanism. Exercise caution when drilling to avoid damaging the door's surface.
- Attach hinges to the door slab first, then to the jamb.
- Hang the Door: Carefully lift the door slab into the prepared opening. Secure it to the jamb using the appropriate hardware. Use shims to ensure the door is plumb and operates smoothly without binding.
- Adjust and Test: After hanging, open and close the door several times to check for smooth operation. Make any necessary adjustments to the hinges or shims.
- Install Remaining Hardware: Install the door handle/knob, strike plate, and any other necessary hardware.

Operation
Once installed, your WINSTELLAR door slab operates like any standard interior door, depending on the hardware chosen (hinged, sliding, etc.).
- Opening and Closing: Use the installed door handle or pull to open and close the door. Ensure it moves freely within its frame or track.
- Privacy: The frosted glass panels provide privacy while allowing light to pass through.
- Painting: The door slab is triple-primed and ready for painting. You can apply your preferred color to match your interior décor. No sanding or additional priming is typically required before painting.
Maintenance
Regular maintenance will help preserve the appearance and functionality of your door slab.
- Cleaning the Door Surface: Wipe the door frame with a soft, damp cloth and mild soap. Avoid abrasive cleaners or harsh chemicals that could damage the painted or primed surface.
- Cleaning the Frosted Glass: The SGCC certified tempered frosted glass is designed to be easy to clean and resistant to fingerprints and scratches. Use a glass cleaner and a soft, lint-free cloth. Do not use abrasive pads or cleaners that could scratch the glass.
- Hardware Maintenance: Periodically check all installed hardware (hinges, handles, tracks) for tightness. Tighten any loose screws. Lubricate moving parts of sliding or pocket door hardware as recommended by their manufacturers.
- Paint Touch-ups: If the painted surface gets chipped or scratched, clean the area and apply a matching paint for touch-ups.
