I think it depends on the price point of your home. If its a starter home on the smaller size, then do the big box stores. They are probably the least expensive and you could paint them yourself. If you are in an estate home...more expensive home in your area, then go to a door distributor to get a solid door instead of the hollow doors from a big box store.

At this point you probably need to try a longer screw of the same size if there is anything for the longer screw to bite into. If the screws are into just plywood with no blocking they are liable to continue to come out.

Moonsma, it is an item that I think was once special order and now is avail in 24 30 and 36 inch size and the stock the chocolate color. Nuporte fold Aura home series. 3100-3680 this is the 36x80 size I assume the 30 would be 3100-3080 and so on. the 3680 was 238.00 an the 30" was 216.00 I love the look of the doors and the glass. I was at hd the other day and the door does not have a real quality feel but then again none of the bifold doors really do. the price is right I have considered making my own doors but the hardware would be a pain. I am going to post on the remodel site to see if someone has any ideas for a contemporary bi-fold door.

So here's the completed project with the Centor Blinds. Check out the install video at their website and realize that the casing that houses the blind assembly sticks out from the door unit a good 4-6" and looks shady onside- wish I'd taken a photo of that before having the left and right sheetrock furred out to make the screen flush with the interior walls. The mechanism slides well, but once in awhile makes a large "clunk" about midway that seems like it isn't lined-up straight on the reel-out of the screen side. I emailed Centor for care instructions, as I have a Phantom Screen on another french door that I silicone regularly, and they never replied. The only care instructions I could find were to keep the tracks clean. You see where the blind meets the screen, and there is a full-length magnetic pliable stip attached to make the connection between the two. It is so magnetic (most likely due to surface area of magnetic material, that t it is a STRONG two-handed separation to open the gap. I'm going to run some quality Scotch 32+ electrical tape at intervals to see if I can make separation more manageable. We have "lake" or "rice" flies that hatch at different intervals of the summer, and if they are on your screen or blind, they get crushed-into the material, and need to be removed via tooth-brush, etc. I'd do it again, but I'd check other brands to see if there is a comparable option that is US instead of Overseas-based.
