Troubleshooting Guide
Adjusting Door and Lock
Adjusting Door and Lock
1. Flat head adjustment screw on single point lock can be
adjusted to move latch in or out.
2. Lock Keeper (on side jamb) can be moved up or down for
further adjustment.
3. Rollers can also be adjusted up or down.
NOTE: 
When adjusting the rollers, lift the 
active panel up to take the weight 
of the door panel off of the rollers. 
If the panel is still installed while 
adjustments are being made the 
stainless steel rollers can be damaged 
which will effect the performance of 
your MP Doors. Remove the plugs 
with a flat screwdriver. Insert a phillips 
screwdriver and find the adjustment 
screw inside the panel. Clockwise will 
raise the panel up, counter clockwise 
will lower it. All three adjustments may 
be necessary. Over time, your patio 
door may require further adjustment to 
ensure proper locking. Door 
must be shimmed properly during 
installation so it is plumb, level and 
square.
