This medical device is used by dentists and oral surgeons to keep mouths open during examinations and surgeries. Made of high quality stainless steel. Measures 5.5 inches from end to end. Widest setting is 2.5 inches.
very intimidating with the ratchets (vs. Jennings) but reduces oral access somewhat. I added a strap to keep it from falling out/shifting when you're vertical or bent forward. Adjustability gives a good control dimension to play and is also a nice feature for newbies with breathing obstruction fears. Easy to clean, easy to use....produces lots of humiliating drool too.
