T-slot nuts are used with workpieces on machine tool tables. The T-slot nut slides within a T-slot track while the workpiece is attached with a threaded clamp. They are also used on extruded framing when building structures and machines. May 05, 2008 IIRC you only take the half of the port height for slot ports. If you are using pvc piping, it's not really a slot port. Just remember to keep it atleast a port radius.
