What Size Are The Bracket "Rails" That Come With The Ark Xtreme Off-Road Jack ORJW750BD

Question:

Hi. I am interested in the rk Xtreme Off-Road Swivel Trailer Jack w/ Dual Wheel - Sidewind - 10 Lift - 1,650 lbs - Black Part Number: ORJW750BD. I have a 16 foot tandem utility trailer with an existing jack that has a foot but no wheel. I’d like to add this jack to allow me to move the trailer when not attached to a tow vehicle. My question is the width of the mounting hardware—specifically the rear “rails” that attach to the back of the tongue and bolt to the mounting plate. I have a factory installed utility box that has about 3/4 of an inch clearance between the inside of the tongue and the box. I need the width or depth of the mounting channel “rails” to see if they will fit between the tongue and the box. Thanks! Brad

Hey Brad, thanks for reaching out. We have a utility trailer here at our shop with the Ark Xtreme Off-Road Swivel Trailer Jack on it, so I went out and measured the bracket "rails". They are approximately 1.10" wide x 0.92" deep. If you have only 3/4" of clearance on the inside of the tongue, I'm afraid these are going to be just a bit too big to fit.
