The Starter Kit comes complete with the Reversible Featherboard Attachment, the Universal Mounting Base and two MagJig 150's. Once you have this tool, get all the other great tool attachments and simply mount to the base as needed.
The Vertical Attachment Is Really Three Tools In One. When used with the Magswitch Pro Featherboard, the Vertical Attachment creates an adjustable, stackable featherboard unlike any other on the market.
