The GMP Tools Duct Clamp, 2 in, Tru SDR (vendor part 89097, Millennium part 494218), fits GMP's Tornado cable blowing machine to hold a 2-inch duct sealed during jetting operations, keeping pressure from bleeding off through the duct entry. It's a standard changeover clamp for crews running Tornado blowers across mixed duct sizes on a fiber build. Machined for a tight, repeatable fit, it holds up to frequent field swaps. Stock it with other Tornado clamp sizes to cover the full duct range this blower handles.
