Smart Pro 4H Black Polar White Bi-folding doors Belldinni Modern Interior Door
Modern design: Smart Pro 4H Black is inspired by Scandinavian interior design, characterized by simplicity and functionality. Pure Flush construction will favorably highlight the advantages of the surrounding interior while remaining a self-sufficient and striking element of home design. The distinctive feature of this interior door is the four horizontal black aluminum strips that create an elegant visual effect.
Door construction: the door is strong and durable due to a solid pine door frame.
Door filling: engineered solid core is an innovative eco-friendly wood fiber material with 12.5 lb/ft³ density. It is responsible for soundproofing and keeping heat inside the room.
Glass: white frosted tempered safety.
High-quality finish: the slab is coated with wear-resistant enamel (Polar White) in several layers using special equipment, which provides a perfectly smooth surface and protects the door from external influences: scratches, moisture, and temperature changes.
Warranty: 2 years.
Easy door hanging: EZ-Hang is a unique seven-bracket door installation system that can be used at any stage of construction, eliminating the need for shims. With this patented technology, hanging an interior door is five times faster. The advantage of the EZ-Hang is that the attachment is adjustable: there's no requirement to bend or alter the bracket, and it is suitable for either or both sides of the door, with or without drywall.
Interior door installation instructions:
- Draw a vertical plumb line on the drywall about 1/2″ in from the rough opening on the hinge side.
- Attach the brackets to the back of the door frame using the 1/2″ screws provided.
- Starting at the top hinge, match up one of the bracket lines with the level line drawn in step one. Screw the interior door to the wall using the screws provided.
