Another thing he's very particular about is the screws in the switch plates on his walls. All screws must match with the groove positioned horizontally.
Can you relate?
I have to admit, while I don't go around my house re-positioning my switchplate's screws, if I do remove and remount a plate (say, when painting a room), I also line up all the screws to match.
"Line Up the Switch Plate Screws" is a dangerous game to play, as you don't want to leave a screw too loose, but over tighten one and "snap!" - your plate cracks.
Alleviate all your switch plate woes with screwless covers. They're simple to mount, easy to clean and are a remarkable way to update the look of any room.
Screwless switch plates come with 2 plates - a mounting plate (or sub-plate) and the finishing screwless cover.
Here's How to Mount Your Screwless Lutron Switch Plate:Step 1: Position the mounting plate on top of the devices in your electrical box.
Step 2: Screw mounting plate into the available screw holes in the devices using provided mounting screws.
Note that the screwless cover plate will snap into the slots in the mounting plate (highlighted in orange in the image below).
Step 3: Align cover plate over mounting plate and push until it fits securely into the mounting plate's slots/grooves.
That's it! Now enjoy your new, modern screwless wall plates.
Note: This guide shows a Lutron brand screwless rocker plate for 2 switches, but most screwless covers are mounted in a similar fashion.
