How you install a hook into the ceiling depends upon the material you're installing it into. In many cases, it can be as simple as screwing the hook in, as is the case with hooks installed into a wooden ceiling rafter. Hooks installed into a plaster or drywall ceiling, on the other hand, will require the addition of special anchors during installation. If you're installing a hook into a concrete, you'll need to use a few special tools and materials to ensure that your hooks are securely fastened.
