Sliding door problem

[COMPOST CORNER]

The door of my 6'x6' polycarb Gh comes off easily in strong winds, so much so that it currently resides in my shed until I can get it fixed.
Would adding a couple of extra guide wheels to the top of the door help the situation?
All suggestions gratefully received.

I had the same problem CC so I put a couple of brackets either side of the doors then a length of 2"x1" across the doors to stop them blowing off.

Is the door properly fixed to the bottom slider, on my GH you have slide the door on from the side, are there any adjustment points top or bottom that allow you to tighten the door up but allow it also to slide.

Don't know if this makes sense :-)

Mine only attaches at the top, so i usually rest a half concrete block at the bottom corner to keep it in place when shut.
Hope this helps

The door is back on, I hadn't realised how loose the bolts at he top had become, so these are now tightened up.
Fingers crossed.
