Not the most technical question here but has anyone found the best way to cut a faceplate down that doesn't fit into a corner? I need to shave about a 3/8" off a 3 gang to fit. The prior screw style faceplate was also cut down. I tried a mitre saw and wood blade and it just shattered. I've found fine tooth circular and jigsaw blades work well on PVC and before I start to experiment I'm wondering if anyone has found the best saw / blade combo when you need to cut off a slice of a screwless faceplate. BTW the underside cut fine but the top snap in piece shattered. I think I just got lucky on the bottom piece.
