My DB bars are 14" spinlock....standard. All of my plates are standard. Not enough room to add more plates to my bars. So I go to google looking for 16" standard bars. Unbelievably, I find nothing in the states longer than 14" standards. Anything longer is Olympic. I can find 16" & 18" standards in U.K. on several sites. WTF.....I NEED 16" DB BARS!!!!!!
