My husband and I are remodeling a 100 year old home. We have a set of beautiful pocket doors that are suspended by a top wheel rail system, The doors and the rails are in excellent shape. The problem we are running into is we need a part, where can we get a part for a 100 year old pocket door. I have searched everywhere for a replicated salvaged part and have had no luck. I wish I knew what the part is called, it snaps into the hardware that is on the door to connect the rail, it kind of resembles a key.
