Multi-Fold Hardware for your Closet Door Needs
Multi- Fold Hardware
Series 1 HBP Multi-Fold Hardware Sets
Looking to use folding doors for a closet or walkway—but need more flexibility than a standard bifold?
Our Series 1 HBP Multi-Fold Hardware Sets allow you to:
-
Use more than two doors folding in one direction
-
Configure all doors to stack to one side or open from the center
How to Order the Correct Hardware Kit
1. Determine Track Length
-
Measure the total width of your opening
-
Select the appropriate track length
-
Tracks can be cut down to fit your specific application
2. Choose Your Door Configuration
-
All doors folding one direction:
-
Requires one Base Set A kit per opening
-
-
Doors opening from the center (split):
-
Requires two Base Set A kits per opening
-
3. Calculate Base Set A Kit
-
Used to connect door pairs to the jambs
-
You will need no more than two Base Set A kits per opening
4. Add Additional Doors (Add on Set B)
-
Use Add on Set B kits to connect additional doors beyond the first pair
-
Quantity depends on the total number of doors in your system
This system gives you the flexibility to design a folding door setup that fits your space perfectly.
If you want, I can add a quick example diagram or sizing chart to make this even easier for customers to follow.

Here’s a clearer, more structured version:
Add-On Set B Kit
Add-On Set B kits are used to connect additional pairs of doors along the length of your track.
How It Works
-
Base Set A kits attach the first pair of doors to the jamb(s)
-
Add-On Set B kits are used to connect any additional door pairs
Examples
-
Three pairs of doors (all sliding one direction):
-
1 Base Set A kit
-
2 Add-On Set B kits
-
-
Four pairs of doors (split in the center):
-
2 Base Set A kits
-
2 Add-On Set B kits
-
This setup allows you to expand your system easily based on the number of doors and your desired configuration.
