This two part how to video series demonstrates how to install a towel rod or towel rack (remember click on chapter two for the hollow door video instructions). In the first video, your instructor takes you through all the necessary steps of installing a towel bar: measuring, screwing, and assembling. The second video demonstrates how to hang a towel rod on a hollow door. Hollow doors require an extra step when hanging a towel bar. You need a few more tools, but the end result is a towel bar that is anchored nicely and looks good, too. Good information for remodeling a bathroom.
