The Liniar bi-folding door range has a wide variety of options when it comes to sizes and opening configurations – with the ModLok™ version up to 7 panes wide.
Our door pane numbering works like this:
• The first number shows the number of doors in total within the frame.
• The second number shows the majority of doors folding back to either left or right.
• The third number shows the balance of doors opening in the opposite direction.
So, a 4-3-1 bi-folding door would be four panes wide, with three doors folding back to one side of the frame, and a single opening door on the other.
