I think it will work just 1/4 " difference. Adaptor would probably be the most inexpensive way to do. 1" Bulkhead 10 Bucks, Heavy duty sounds expensive! ****, things just cant go smooth. I find that alot. Smoothe to me is come home & have everything. Does'nt happen. Never I started a pile of things that I might need. Take all the extra crap I buy back except one or two, just in case I need it at odd hours. Most of the time need something else, never fails. Trip to HD 10 Minutes away I still hate it. LOL, hope you get it knocked out.
