If you have access to Air Conditioning Metal Layout by Joseph Kaberlein you'll find instructions for a rectangular to triangular transition. Plate number 95 in my edition (1954). This book is very good for unusual/uncommon fittings but it can make your head spin a bit. I learned to do the initial layouts on cardboard or building paper--saves a lot of metal! Out of curiosity, what's your application?

Thanks for that, yes I have that book, will have to dig it out and take a look. Like the idea of using cardboard first, that sounds sensible. It is for kitchen ventilation ductwork, to fit in roof space with minimal room passing through roof trusses-hence the triangular shape. Thanks for the help I will let you know how I get on .

I'm not having any luck either uploading or sending you a private message and patience is waning. Email me--Bill Kane (chev87.2@gmail.com)--and I will send it to you.
