Product Information

Students love to fiddle. If there's a knob to be spun, a lever to be turned, or a button to be pushed, they will do it, especially if they are told not to. These unique affordable safety devices were designed by teacher John Nevins. They come in either one jet or four jet models and prevent students from &"messing&" with the handle or other mechanisms. Constructed of heavy-duty plastic, students can see but they cannot touch. Comes with lock and key.
