Making the Mounting Hole to Install a Sliding Glass Door Lock

Video Transcript

"Right here, that holds the glass in, keeps it from shaking. That runs as far as the glass goes, so as we tap on it, we'll hear a distinct change that tells us where the glass and the insulator end. I'm going to move the microphone down so you can get a bit better hear of that. When it goes to that higher pitch, we know that that's a safe place to drill, and we don't want to drill any higher than that. I've marked out here. Now, as we take the lock and put it in here, we're simply going to drop it down and let it set on the track. From that point, we'll lift it up about 1/8 of an inch so it doesn't rub on the track when the door opens, and that will tell us where we need to set the lock. I'm going to push the lock in, verify that it's hitting below where the glass is, and it is. I'm going to use a Sharpie marker and I'm going to run the lock all the way to the edge of the inside of the door frame in here. I wind it up, and then I'll simply take my Sharpie and just mark that hole nice and good so I know where it sits, and that tells me where to drill."
