Frequently Asked Questions (FAQs)

1. Where do you put the handles on an internal bifold door?

In most cases, the ideal position is with the bi fold door handles located in the horizontal centre of the middle two doors, as this acts as a compromise between smooth opening and smooth closing, keeping friction to a minimum to avoid excessive pressure on the tracking system.

2. Do bifold doors need a handle?

The functionality of your handle is very important and whilst many often go for a standard hinged handle, we believe that a classic knob or D handle usually looks best. These handles are practical, sturdy and very sleek, and as an internal bifold door doesn't need a bolt, a hinged handle isn't required.
