My toilet bi-fold door came off the door frame as I tried to open the door. There was difficulty opening the bi-fold door. I used some force and the whole door came off. Fortunately, I was able to hold the door firmly and prevented it from hitting my head and toes. If not I would have serious injuries. The bi-fold door is quite heavy as it is made of metal frames 

The top roller broke a leg. I think I need to replace both top rollers. Where can I buy these rollers. Any shop in Singapore selling these rollers?

My common toilet bi fold door also spoilt.
Cannot lock and now almost track no more...
Trying to get one cheap cheap type of bifold door too.

Those 10 pcs one, I think are not suitable - size does not look appropriate. I think the set of 4 pcs are more suitable - the size (5cm,) durability - fit for door weight 10-15kg. Its best to buy physically front the store if they have a branch here.

I bought this in shopee a few years ago and quality was good. Yah, but you're right, I ran the risk of buying the wrong one. However, the price was like 20% cheaper than physical shop so I decided to give it a try. Not expensive things anyway.

My common toilet also cannot lock. That one can wait since the door can be closed. No one will push open the toilet door since the door is closed. 
My concern is the Master Bedroom door as it has no door now.
