I don’t think it was intended as a smart comment, he was asking for a better picture of attachment point, which I would also like.This is stainless steel 18 in roller cage. The block on the bottom opens up and locks onto the threaded portion of the extension pole. Made by a very small company about 15 years ago that made specialized painting equipment. Very simple design that worked very well. Just looking for the name of the company ,not smart ass comments.
