Well, I figured I would post this because lots of people seem to be installing this time of year. I made this to help me pull my liner down my chimney. This was made with pieces I had laying around the house, but could be bought for less than $10 at a hardware store. This is a piece of track from a stainless steel wall stud system. I basically cut and bent it into the shape you see. I took an I bolt I had laying around and attached it at the top, and used some old 550 cord to pull it down the chimney. I rounded it were it seated against the inside of the liner and secured it to the liner with sheet metal screws. It took less than 5 minutes to pull my 5.5 inch liner down a 7x11in. I.D. chimney.
