Sliding glass door not closing flush

I purchased an Anderson sliding glass door and after installation I noticed that When I slide the door to the closed position, the door seats at the top and not at the bottom. I Checked for squareness after I put the door frame in and it looked good. I proceded to shim around the door between frame and studs and all looked good. It wasn't until I put the sliding door in and slid the door to the closed position when I noticed it wasn't square. Maybe I shimmed too much on the top end of the door Jam, making it bow more at the top and thus seal there first? Is there a good way to fix this? Should I shim the bottom more or the top less???

 

If it's slightly out of plumb, adjust the rollers by removing the caps on the bottom rail and turning the screw to lift the rollers accordingly.

 

johnam,

I adjusted the rollers as high as i can go without making it too difficult to move the door and it still doesn't seal square. Any other thoughts?

Thanks

 

I hope that you only raised the roller closest to the jamb? Other than that, I don't know what you should do.

 

If you already trimed your door, remove trim. Sounds like you shimed to much on 1 side and not enough on the other. I would close the door to about 1/4" daylight showing, and reshim untill you get an even reveal. Anderson nail on fins are pressed into place so you will have to recaulk the fins when you are done, If you move the bottom sill during reshiming, recaulk that also inside and out and up atleast 1 to 2 inches on the inside ( to make sure no weather comes inside )
