In this video I demonstrate four different types of wall hanging devices designed for carrying heavier loads. In addition, I've included below, a link to a fifth type called a threaded wall anchor. One of these should work for hanging just about anything from larger pictures and heavy mirrors to shelf brackets and cabinets. With the possible exception of the toggle bolt, all are intended for use primarily in drywall or wallboard. With a basic understanding of the differences between these and a clearer idea of how they work, you'll be able to choose right one for whatever hanging job you're tackling.
