Cylindrical squirrel baffle for poles 1/2" to 1-3/4" diameter. 14-1/2" long, 7" 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.
