Attaching to the bottom of seed feeders, these trays will catch all the seeds and seed casings that are discarded or dropped as the birds feed. Helping to keep lawns or flowerbeds clear of debris, the trays also act as secondary feeding platform for birds to feed on. Attaching to the base of any feeder with a 2cm screw in attachment, the trays come complete with connecting bolts that are easy to wind into place - and just as easy to remove for cleaning if necessary. Please note- the only feeder in the Selections range with the tray attachment is the GFK611 Premium Feeder with Aluminium Lid and Base * Connecting bolt included * Drainage holes in base * Measures 20cm across * Set of 4 Feeder not included
