At just over 18" (470mm) wide this giant guard/tray could stop squirrels from reaching feeders and also doubles as an easily cleaned bird table too. Fits poles 1" (25mm) in diameter, made especially for the Droll Yankee Garden Pole.Top Tip: site your garden pole at least 8' (2m) away from trees and buildings and the guard 4' (1m) op the pole.
