Yes it is the Westpak. I've got the 4 jet low profile with 1.75" tube. It will take both a 1.5" vac hose and 2".I've just changed from an inferior slotted glide to a Greenie Hybrid running from my Scorpion and the results are absolutely stunning. No shortage of performance. It will only pick up small deposits of fluff though compared to my old slotted glide which would take virtually anything. I wouldn't want to change back though. I haven't tried this wand on a twin vac portable, and Mark could well be right about using on a T/M rather than a regular porty, esp. if it's vacuum optimised.The same wand is available with a 1.5" tube if you prefer and it may be a more viable proposition.Safe and happy cleaning Ken
