You’ll need a #2 phillips head screwdriver and a putty knife for this project. Begin by removing the four adjustment plugs located at the bottom of the door panels. With the door slightly open use a putty knife to raise the weight of the panel off the rollers. This allows the adjustment screw to be turned without damaging the screw. Use a #2 phillips head screwdriver to turn the adjustment screw clockwise to raise the panel, and counterclockwise to lower the panel. Adjust the door panels as desired. Next locate the set screws on all four multi-point lock strikes at the top and bottom of the door. Remove the screws closest to the handle. Now slightly loosen the set screws closest to the center. Starting with a passive panel, position the panel so that it engages both the top and bottom strikes. Once you achieve a good locking position, release the lock. Slide the panel open and tighten the screws on the passive side. Test the operation and locks again before reapplying the two set screws. Now position the active panel and multi-point strikes into a good locking position. Once you achieve a good locking position, tighten the two screws on the active side. Test the operation of the locks on the active panel before installing the final two set screws on the multi-point lock strikes. Finish by replacing the four adjustment plugs at the bottom of the panels.
