GEORGE ENGLE: On behalf of Expert Village, my name is George Engle with Mr. Fix-It Handyman, Inc., here in Miami, Florida, and today I'm going to be showing you how to install a bi-fold door. So, what I like to do is go ahead and put the screw in first. So that it comes out to the other side, and then this one you can pretty much hold the back side of the drill while you just screw this one on. That way you make sure it doesn't come to the front and if it should come to the front, you can always change out your screw to a shorter one. Okay, so that's on there, pretty good. That's going to help us to open up and close the door. We've got these other three pieces that we discussed earlier. This is the bottom piece, the one that's going to adjust the door. The one that holds into place and the roller that's going to keep in the track and help you to slide the bi-fold open and close.
