If you're looking to add some metal legs to a glass table top, there are a few things you need to keep in mind to ensure a proper and secure fit. First, you'll need to find legs that are the appropriate size and shape for your table. Once you have the legs, you'll need to clean both the legs and the table top to remove any dirt, dust, or debris. Once everything is clean, you'll need to apply a silicone adhesive to both the legs and the table top, and then carefully line up the legs with the table top. Once the legs are in place, you'll need to apply pressure to secure the bond, and then allow the adhesive to dry for the recommended amount of time. After the adhesive has dried, your new metal legs should be securely attached to your glass table top!
