Hi! Thank you for asking about the Reed Manufacturing 306NT Main Vise Nut. We are sorry to be the bearer of bad news but, according to the manufacturer, the 2306 and the 306NT are not interchangeable. It seems that the Reed 2306 is a Tripod Vise. It is not on Plumbersstock yet but if this is the part that you want, feel free to contact our Customer Service Department at 435-868-4020 from 7 AM to 7 PM MST (Mon-Fri) or through firstname.lastname@example.org. They will be happy to assist you in placing the order. Should you have further questions, please ask away! Thank you for visiting Plumbersstock.com. Have a great day!
