Drilling the Second Hole to Install a Sliding Glass Door Lock

Video Transcript

Hi there! I'm Daniel on behalf of Expert Village. In this clip, we're going to be drilling the second hole on our sliding glass door lock installation. Up to this point, we've drilled the first hole and marked for the second hole. Drilling the second hole is basically the same as the first. The only thing to keep in mind is that you're below the glass this time, and occasionally inside the door, you'll have a place where there's a screw that attaches the horizontal and vertical outside aluminum planks. You just want to make sure, once you break through, check in there with a flash light and make sure there's nothing behind here that you're going to hit. You may need to drill a little bit farther on the second hole than on the first hole. Again, you're not worried about hitting glass, you're just simply worried about the horizontal aluminum structure getting in the way. Okay, so we're going to punch a little dimple on the aluminum like we did on our first hole, simply to prevent our drill bit from wandering. Again, the only thing that's important here is to create a dimple. We don't want to try to punch through it with our punch. Now, we're not worried about hitting the glass here, because the glass will have ended quite a bit higher up. But we will be running into the track most likely, so we'll be drilling at a little bit of an angle on this one. Now, often times the aluminum is a little thicker here or we run into the horizontal part of the door that provides for a little bit of resistance because of more aluminum being there. If you have any question or any doubt, you can simply take a screw and screw it in or take your drill bit out of the drill and just make sure that it'll punch through about the length of what you're looking at.
