Mushroom Vent Cap

The mushroom vent cap has molded-in steps to accommodate either 3” or 4” roof vent pipe.  Manufactured and assembled in the USA by Plastic Oddities, “Friend of the Plumber”. Cap locks into position with 3 flat-end bolts, which will not penetrate the pipe, unlike pointed bolts.  Helps prevent rain, leaves, debris, flying insects, and animals such as squirrels from entering vent pipe.  Also works on portable toilet enclosure vent pipes and other exterior pipes that need to be protected. Quality Plastic Oddities parts – since 1975.
