Dimensions of Inner Tube on Bulldog Square Jack # BD180354

Updated 04/04/2019 | Published 04/03/2019

Question:

Need to know what dimension the larger inner tube is. The overall size matches one I need to replace, but I need to confirm the tube is correct to match the housing already welded in place on my old trailer. My old one has outer dimension on the tube as 2.75inch sq whereas the 180354 specifies 3inch square OD. Wasnt sure if the outer tube is simply thicker than mine or if the full jack is different. The original trailer manufacturer does not know what is on the trailer. Please let me know. I cannot get through to Bulldog direct.

I went out to our warehouse and measured the inner tube (not the drop leg) on the Bulldog Square Jack # BD180354 to be right at 2-1/2 inches x 2-1/2 inches. The outer leg of the jack measures 3 inches x 3 inches like you mentioned.

I have attached an image to assist.
