Avoiding Falling Furniture During Earthquakes
We are considering using “L” brackets to attach tall furniture to walls to help keep them from falling over in case of an earthquake. Will this damage the walls or studs if and when this happens?
Make sure that the “L” brackets are firmly screwed into the furniture and into the wall studs. We don’t think it would be wise to use molly screws or toggle bolts for such a purpose. Make sure that the screw penetrates into the stud at least one and one-half inches. Remember to consider the thickness of the wall covering and or paneling when selecting the proper screw.
If your wall is covered with half-inch drywall you will need at least a two inch long screw. If your wall is plaster you will need at least a two and one-half inch long screw. When installing screws into old dry studs it is wise to pre-drill a small pilot hole first to prevent the screw from splitting the wood. To make the screw easier to install wipe the threads across a wet bar of soap. The wet soap acts as a lubricant for installation, and when it dries it helps to hold the screw in it. And good luck!
