Diameter of Foot Plate for Jack-in-a-Box Camper Slide-out Supports


I just purchased the #JB-20 jacks for my 1996 Keystone Montana 5th wheel. Can you tell me what diameter the base of the jack is? Thank you.

The bottom foot plate of the Jack-in-a-Box support jacks, part # JB-20, measures 4-1/2 inches in diameter.
