Very heavy duty, weld on style trailer jack. The retainer pin is connected with a chain. This is a brand new jack, and these are pictures of the actual jack I took. They are ready to install. I have two of these available that. These retail for about $80 - 100. I can vouch for the immense strength of these Bulldog jacks, they are phenomenal equipment that will hold up for the long haul. I think half price is a great deal for somebody that needs these for their trailer or project. Come get them. Qty 2 - $40 each. ** If you are seeing this item... Then it's AVAILABLE.. I am very vigilant and courteous to buyers, and I immediately remove my ads when something is sold. I am a private seller in a commercial location in North St Petersburg FL. I am very easy to locate. Quick and easy transactions. Thank you for your time.
