Trays beneath tube feeders are great, offering an additional space for the birds to sit and eat, as well as keeping seed from dropping to the ground beneath. 

Not every tray will fit every tube feeder.  It's always our advice to first ask the brand name of your feeder. If that brand name also has a tray, it should be a good fit.  Some of the newer trays have multiple ways to connect, giving them the ability to fit many different brands securely. 

Color choices are available from some companies, clear is usually an option also.
