My 5? Pelli door does not close right anymore. If you do not lock it, the door will creep open about 1/8? on its own. You can hear it isn?t sealed properly and feel the draft at the separation between the two panes. Are the door keeps or latches at fault. Thank you...Vin Christian

I have a few thoughts. It could be that the rollers need to be adjusted: to be more specific, possibly the rear rollers might to be raised just a little to keep the door from rolling open. It also could be that your keeper is worn. Lastly, see if there is some type of adjustment in the handle. Check to see if there is a type of adjustment screw on the handle that you could play with to see if that makes a difference.
