When it comes to securing thin sheets of plastic or metal together, especially in situations where you can't access the back end of the joint, rivets are a very effective method of fastening with low installation costs.

A grommet is a two-part piece of hardware that is pressed together through a pre-punched hole in a piece of fabric. A quality grommet is normally made from brass or stainless steel. These malleable metals will flare and roll when the grommet is installed to lock the two parts together, sealing the fabric in between.
