I have this frame with the king size rails. I bought it for $50 from an ex guild member who was moving. I never used it for handquilting so I put a quilt on it to baste. It works great for me. The rails on mine are wood so I use the large quilting thumb tacks to hold the leader cloth to the rails and then hand baste the quilt top and backing to the leaders. I only use it for king or queen size quilts that I don't machine quilt in sections. Mine folds up great, it is almost flat against the wall. It must be an older or different model. There is no metal or black pieces on it . Even the gogs are wooden.
