Will Husky Lube Plate Fit King Pin on Trailair Flex Air 5th Wheel Pin Box

Question:

Can you tell me what the Pin Size is for the Flex Air® Pin Box With Long Tow, L05, 18K, Model #328492? I currently use the Husky 12inch Lub Plate on my Curt 20k 5th wheel and it states that the Pin needs to be 2-7/8

The Trailair Flex Air 5th Wheel Pin Box # LC328492, which replaces a Lippert 1621 pin box, has a standard 2" king pin. The Husky Lube Plate # HT34914 will still fit though as the 2-7/8" diameter referenced is talking about the upper "lip" area right under the pin box (see attached).

These 2 pieces will work great with a Curt 20K 5th wheel hitch.
