Please be aware that each image or PDF's for our internal folding doors show a position of a flush pull, hinges, slip bolt etc but the position of each item is very dependent on how you and your carpenter decide the doors should open.
There will be occasions when you may decide that the flush pull is better fitted in the centre of the middle door for a 3 door set or indeed a latch handle is fitted on the main opening door, you may also decide that you do not want to fit the slip bolt - each and every decision is yours to make - just decide before fitting any of the above items.
The small door stops (25x12mm) for some of the configurations will have to be "offset" so one leg allows the main door to close against it in a traditional manner whereas the same door stop will be fitted on the opposite side at the other frame leg.
Configuration choices are:
- 2+0, two doors opening left or right.
- 2+1, two doors on one side and one opposite.

Our unrivalled experience in fitting folding doors means we can advise on which doors in our product range can be cut, and by how much, in both height and width.
If you’d like more information on the entire measuring and fitting process, visit our Help Section.
When measuring your folding doors, ignore the current door size and follow the advice below. Be aware that in most cases there are locating pins to the top and bottom of most bi-fold doors
Width: Measure each opening between the frame at the top, the middle and the bottom.
Select a door set that fits the widest size. This is because the widest size can be adjusted by you to suit the narrow area of any part of the opening without compromising the stability or affecting the look of the doors - small adjustments to each door edge can help you find just the right size but is not a recommended process for exterior doors.
Height: Measure from the carpet/floor covering to the underside of the timber lintol.
Thickness: Now and only now do you measure the door to find out how thick it is at present. With interior doors you may have to compromise and fit a slightly thinner door. This does not normally present any problems.
All of the Internal bifold (single) sizes quoted are to suit "openings" of that size, the folding door kits are always smaller by about 10mm -15mm in width and the height is smaller by 35mm-40mm to allow for the addition of the track which goes above the door set, the track is included, these clearances allow the correct operation of the Bifold track and associated hinge pins.
