On the technical drawings, under step 2 - there is a table on the top right of the page which is obviously relevant to the door width. Please can you advise how I use this calculation in the build, as it is not clear?

The doors I want to use are 43mm thick. Obviously the end pivot point would need a bit more space for clearance, and when folded, they would take up a little more space. Is this okay, or are there any other issues to be aware of?

Can I fit a 4 door system to one side, and then a 2 door system to the other?

Asked by James Addy | 18/01/2018, 21:09 | 1 answer(s)

Could a 4 door system be attached on one side, and then a single (normal) door hinged for general use be fixed on the other side? And if yes, is there some flush locking systems to 'bolt' the bi-fold doors in place when the panels are closed?

I have bought 3 sets of Herkule Plus 40 kg I am going to build 6 panel door attached to one side only How I have to calculate width of each panel? Could you explain what x variable means in reality on pic. 2A 2B 2C ? I think it is gap from side wall to side of hte door. Am I right ? And if so why x changes with thikness of the panels How constant 5 on pic 2A is calculated? How constant 8 on pic 2B and 2C is calculated? Thanks beforehand

Does a 4-door set includes fixings to allow a 2 x 2-door system where each pair of doors pulls to the outside? If not, what is the right hardware to achieve this?

Asked by Jo | 21/12/2016, 15:01 | 1 answer(s)

What is the thinnest door thickness that can be used? The instructions suggest 16mm from the table indicating dimensions "G" and "x". Will the hinges fit a door as thin as this? or would they need to be face fixed rather than into the sides of the door?

Hi, Can I recess the top mounting rail into the top of the frame so that the door then fits flush with no gap? Thanks

Asked by Stuart Horwood | 03/10/2016, 13:59 | 1 answer(s)

The instructions suggest that if you want the door to butt up against each other when closed, the hinges should be mounted on the outside face. Is there any reason you should not recess the hinges into the edge of one door, so they close flush still?

Asked by Simon | 18/03/2016, 08:45 | 1 answer(s)

Can the doors only open to the left when facing them, or can they open either way?

My door is 2040 High, what height should my opening be to accommodate the track . Alternatively can I fix the rail to the wall and if so what gap would there be between the wall and the door (door is 40mm) Thanks

is it possible to cut the track down to suit a 27" opening

Asked by jan | 20/03/2015, 09:36 | 1 answer(s)

I assume max width of opening is limited by track size - eg 2.40m
