The Janome Spool Peg 50567005 fits a few of the slightly older models. This horizontal type of spool peg is susceptible to damage when picking up the sewing machine. Sometimes you might accidentally lift the machine by the spool peg, instead of using the handle. To replace this type of spool peg, the covers of the machine have to be removed. The peg is pinned inside.
This Janome Spool Peg will fit the following models,
