It says range is 13 to 10 AWG.

When ordering these you have to realize this is ala carte - The connector bodies, hoods, flanges, sealing covers are ordered individually. Great way to get what you want but you need to think about it. I miscounted pieces when I ordered and had to place a second order.

Allied is a fast shipper, they will add $5.0 on small orders. How small I don't remember.
