David Marin : I worked off and on for years in a small hometown type hardware store ! Generally what happened was the big box store sold an appliance,
and then we had to help them find the " Goes into " that would finish the installation, with a 30 mile round trip to the next big box store if we couldn't
sell
them what they needed !
In this case, while you might have to fight to get the two parts together the most important part of the build is getting the '' Ts " that you need and then the
caps that fit. If all you can buy is the un-crimpt ones that works better than two crimpt ones and you need to hammer the crimping out without stretching
the metal !
Ask at the hardware store if they have a stovepipe crimper ! Do NOT be surprised if they want a $50 or $100 Dollar deposit to loan it out for 24 hours !
A # 10 vegetable can is 6'' inside diameter, and I have used it inplace of a cap when I had failed to account for all the clean outs I needed !
Also! It is more likely that you will need a pair of straight and curved sheet metal cutters, a saber saw sucks at cutting Pipe ! Big AL
