    RV Jack
    This is an OEM jack used in many RV's. It is high quality and made in the United States by one of the premier parts manufacturers. Customer service at BAL a division of NORCO helped me find the exact replacement for he damaged jack. In my case the jack was promised for 3 day delivery and was delivered the next business day.
