I found these at my local Canadian Tire. They are quite simply, awesome! They install quickly and easily and have fantastic holding power and strength. They come in different shapes and sizes.
They install useing a very sharp, course thread screw, the type used to screw into drywall. They screw into press/particle board like a hot knife through butter.
