Cylindrical squirrel baffle with a dome top and a scalloped (the scallops complicate footholds) edge bottom, for poles 1/2' to 1-3/4" diameter. 16-3/4" long, 6-1/4" in diameter. To keep squirrels from getting onto your bird feeder, place your pole-mounted feeders 8-10' away from railings, roofs or trees. Squirrel baffles should be a minimum of 4' from the ground to protect the bird feeder. All steel (can't be chewed)
