If you have the Expo portable spray booth or similar this will do the job.
I have two spray booths that I wanted to fit next to each other in tandem, but one was the new design whilst the other was the older (original?) design. This meant I had to adapt the old one to fit the adaptor. Using the new one as a guide, I had to cut out the slots to allow the tabs in the adaptor to fit.
If you're happy to make the modifications, I doubt you'd be disappointed, otherwise you may want to steer clear. Also, I was able to fit mine through a wall using only the adapter and I haven't used the hose or window nozzle. If the parts were available separately I'd be happier, but I bought the kit knowing I may not need all the parts.
Clips that hold the hose to the spray booth are too weak and broke off far too easily on first fitting.
The length of the hose is too short and unless your bench is under a window you need to purchase one or more extensions.
