Enhance the functionality and durability of your bifold door with high-quality accessories like hinges, handles, lock seats, and so on.











To install bifold doors, follow the steps below:
Ensure the doorway is level and the frame is secure.
Secure the top track to the header to guide the door's movement.
Fix hinges to the doors, connecting the panels securely
Insert the door pivots into the top track and bottom pivot bracket.
Fine-tune the door's alignment for smooth operation.
Attach handles and check for proper function
To paint a bifold door, first remove it from the track and lay it flat. Clean the surface, sand lightly, and apply primer. After the primer dries, apply paint using a brush or roller, allowing it to dry between coats. Reinstall the door once fully dry.
Bifold doors come in standard widths ranging from 24 inches to 72 inches, with heights typically around 80 inches. Custom sizes are also available.
Measure the width and height of the door opening, making sure to measure at the top, middle, and bottom for width. Use the smallest measurement to ensure the doors fit properly.
Bifold doors typically require a bottom track to ensure stability and smooth operation, but some models are available with a top-hung system that doesn’t require a bottom track.
The cost of bifold doors varies depending on the material, size, and brand, ranging from $100 to over $1,000 per door set.
To trim bifold doors, remove the door and carefully cut the bottom or side using a fine-tooth saw. Sand the cut edge smooth, then paint or stain to match.
