If you have a glass table top that you want to attach to metal legs, there are a few different ways that you can do this. One way is to use special glass table top clamps. These clamps are specifically designed to hold a glass table top in place on metal legs, and they can be found at most hardware stores. Another way to attach a glass table top to metal legs is to use epoxy. Epoxy is a strong glue that can be used to attach many different types of materials together, and it will work well to attach a glass table top to metal legs. Just be sure to following the instructions on the epoxy package carefully so that you get a strong and permanent bond.
