Simply put the chair at the end of the rower, place the handle vertically through the "slats" in the back of the chair, and turn the rower handle back to horizontal again and it holds the chain. I have tile floors so the chair was sliding so I added a 30 lb dumbbell onto the seat; if I was not doing the oiling myself, I could have sat in the chair, thus adding a 175 lb dumbbell.
