I need to mount unistrut to my trailer. Do you have square ubolts 3/8 x 1 9/16 at least 5 inches in length with a mounting plate.

Hey Ron, thanks for reaching out!
The closest U-Bolt kit we have to the specs you're looking for is the Trailer Square U-Bolts # 382385UB which measure 2-3/8" x 5-1/4" x 3/8". We don't have a massive selection of square U-Bolts though, so if you have to have those exact specs then you might be better off visiting your local hardware or home improvement store to see if they have what you're needing.
What are you planning to use the Unistrut for?
