Aspects' Round Seed Tray works well on a pole-mounted feeder as well as on a hanging feeder. Tracys can be used on the feeder mounted on a 1/2" side pipe threaded on one end. It is suggested to use a 6 to 7 foot length of pipe. Adding a seed tray will allow more of the seed to be eaten at the feeder and less scattered on the ground. This seed tray will work with any standard size Aspects Quick Clean feeder. (not the Big Tube feeder)
