Which table do I need to use to calculate the stud length with the 4002-N-B grommet?

Question: I got your images correctly. My question is about stud length table to culculate stud length no. Please see the page G-2 and G-3 of your Quarter Turn catalog. It's showing stud length table for 4002 series, but I do not see the word "4002-N3-B". So I'm wondering if we should use the table of G-3 because 4002-N3-B is "Plus Flush Mounting" as well as 4002-N-3. Answer: You need to use the table on page G-3 When you get the value of the stud length number, you simply need to select the next one that is larger. (only for grommets 4002-N3-B)
