Benfield Wrote the Book on Bending

"This book is a must for the beginning conduit bender. Jack Benfield invented the EMT bender and has taught conduit bending since the 1930s. The simple mathematical approach is how I taught conduit bending with the help of this book at a high school trade school and it works. I highly recommend this book for the person that wants to make precision bends in a competitive time frame." - Customer Review, Barnes & Noble Books
