The standard inline jaw is the jaw that comes with every Norvise we sell. Since taking over the company in 2018, customers have asked me numerous times about purchasing this standard jaw separately. Be it to just have a spare, or one for demo purposes, or to upgrade to the new "oecam-lock" locking system, an extra set of jaws is never a bad idea (especially if you travel a lot). Our customers have spoken, and we listened, so in 2018 we made the Standard Inline Jaws available to purchase again.Please Note; this jaw has an outside diameter of 3/8 (.375). Therefore, these jaws may not be compatible with the older Norvise models with the older magnum hubs. Please call or email if you have questions.
