For sale is a Ridged Model 400 Pipe Threader, Serial No.400524. 2" Diameter capacity for threading pipes and bolts. Comes with various dies, hand-operated pipe-cut-off tools, Ridged hand-operated pipe threader and oil pan with Ridged No.2 oil-gun. NOTE: I have done a basic test on this pipe threader, and it runs well. It looks much better than all other Ridgid 400's that I came across in the past.
