The rubber body plug is one of the models of these units and they can be utilized in many different ways.
There are a lot of types of the rubber body plug, and they can be used to plug unused holes, or they can be implemented to protect the device from any water or dirt penetrating inside it. Note that they can be used for firewall applications, in different types of devices and equipment, or they can just be mounted on the wall to add a layer of protection.
