Browse Forums Windows & Doors Re: Centor Bifold Door adjustment 7Feb 21, 2014 1:01 pm There are actually 2 easy ways to adjust Centor Bifold hardware. We actually build a lot of bifold doors using Centor bifold hardware. If you are after horizontal adjustment, look inside the top and bottom tracks near the jambs. You will see phillips head screws in each. From this point its simple. Get a big phillips head screw driver and tighten the screw if you want to tighten the gap at the other end and loosen the screws if you want to loosen the gap at the other end. Should be straight forward. The vertical or height adjustment can be done from outside..... Disengage all the locks and partially open the doors. Then (from outside) you will see all the top hinges that connect to the track. These hinges are adjustable. There is a safety clip that you need to pull down, but once you do it's as simple as putting in a flat head screw driver and tightening the screw. This will lift the doors. So obviously loosening the screw will lower the doors. If you want more information go to my website. Binq windows and doors (just google it). Send me an email through the contact form and I will send you our adjustment instructions. Although it is under the build contract, the supplier should still warrant the products they manufactured. Easy done! Good Luck Re: Centor Bifold Door adjustment 8Feb 21, 2014 2:48 pm joelwindows There are actually 2 easy ways to adjust Centor Bifold hardware.

Easy done! Good Luck Thanks for your reply. I worked out how the doors adjust mainly by trial and error. The tricky thing was working out how the locking mechanism on the screws worked. I have done the horizontal adjustment on the active door and it is now working correctly. I found that all of the vertical adjustments on the folding door top hinges were already at the highest position and the doors are still sticking at the bottom in one section of the frame. The end hinge still can go up further so I will try adjusting that on the weekend and see if it makes a difference as it could be putting all the doors out of alignment. I have a feeling that the problem is with the frame and it is going to be difficult to fix. I'll do some measurements to see if the frame is out of square before ringing the builder. The fact that the hinges have already been adjusted to the max suggests that the previous owner has already tried to fix it. I'm a bit worried that it will be very expensive to remedy and the builder will try and wash his hands of it. Re: Centor Bifold Door adjustment 9Feb 24, 2014 9:42 am I did some measuring on the weekend and it turns out that the door opening is about 7-8 mm lower in the middle than it is at the ends which is what is causing the doors to stick. It is a full 2400 in height at each end, but slightly lower in the middle section. There just isn't enough height in the middle for the doors to slide easily. It looks a bit like like the lintel has bowed under the weight of the doors. Does anyone know if this is common? Re: Centor Bifold Door adjustment 10Feb 24, 2014 9:27 pm I wouldn't say it is overly common. The doors shouldn't be that heavy to bow the lintel down, unless the lintel was underspec to start with. Hopefully whoever installed the doors left a gap between the door frame and the house frame. If this is the case it is simply a matter of opening the doors up, removing the architrave and rescrewing through the top track to straighten the head. If there is no gap unfortunately it won't be a fun or simple exercise to rectify. First step is to remove your internal architrave and check for clearance. If you have clearance, happy days. If you don't then the onus will definitely fall on the builder to fix. Either way I would recommend notifying the builder as it would seem that you may have a structural issue.

Thanks heaps for your help. I'll contact the builder as my next step. Re: Centor Bifold Door adjustment 12Mar 21, 2014 1:49 pm Sadly this is all too common. I see a lot of bifold doors that have trouble working properly after being adjusted to the max mostly because the builder has put a low spec lintel over the opening and has probably just allowed for the load above the doorway never mind another 300-400kg of doors as well. Ripsnorta, let us know the outcome. Stewie Black on light wood does look good. Not sure if it will be as long lasting as a steel finish? 6 6348 I’m in a similar position except I’m after sliding 3 stacking doors. I am on a second-story apartment of which the balcony would not adequately fit any bi-fold or… 5 16126 Current door width is approx 2700, looking to have double doors fitted 820-820. What size does the frame need to be before door jamb? Thanks 0 3545 |
