If you are talking about actual bankers, and the actual bankers have boxes, bankers’ boxes is what you want to write. Bankers’ is plural and possessive—that’s why you need an apostrophe after the s. 

BUT, as one reader pointed out in a comment on my Plural Possessive—Bankers’ Boxes post, Bankers Box is a trademarked brand name, and when you refer to the actual boxes known by this name (and not the actual bankers), Bankers Boxes is what you want to write.

See the distinction? I do—now.

Thanks, catalinda8, for sharing your wisdom.

I was asked this question today:

If John states in a report that he reviewed 3 “bankers boxes” of records, is the correct grammar “banker’s boxes,” “bankers’ boxes,” or “bankers boxes”? Should the “b” of bankers be capitalized? How about the “b” of boxes? Is it a proper name? What do you think?

Here is my response:

Since there are three bankers, bankers is plural, and to show possession for a plural word already ending in -s, you add the apostrophe after the -s:

three bankers’ boxes

Also, you should spell out three and any number less than 10—in most cases, anyway. There are some exceptions, though, like with ages.

Bankers’ boxes is not a proper noun, so no need to capitalize (unless Bankers’ starts a sentence, like it does in this instance).
