I stole some ideas today from the MATRONICS Archive. Having never installed these before I figure it couldn't hurt. Layed out the door holes then transfered them to the strips first. Then I made a template and tested the fit for the spring hole locations. Once that was right I marked the strips Image 1) so I would dimple the correct side, then dimpled the holes.
Image 3) Using the dimensions off the print, the corner springs will attach to two strips. Next->
