This is for a Lot of 6 New Tube Style Feeder Replacement Perch and Port. I believe these are made for older Droll Yankees bird feeder's but may work on brands. These are made of metal (aluminium) Not cheap plastic squirrel/chew resisted. The face plate is about 1-3/8" wide x 2-3/16" tall with a perch length 1-15/16". The port hole size need to installed is about 15/16" Diameter. These could be glued in or there is a bolt hole on the back on the inners side of this part see picture's.
These would be great to repair or a hobbyist bird feeder maker.
