I am trying to find replacements for the safety stoppers r whatever they are called. Many of ours have gotten old and brittle and have begun to break.

Your vent lock looks like an older version that has been discontinued. The manufacturer replaced it with the 26-106. Just compare the face to see if it matches. Ours is 5/16" wide by 1-3/16" tall.
