Wraparound break-apart squirrel baffle for poles 1/2" to 1" diameter. Also 7/16" to 5/8" Square poles. Baffle Diameter is 17". 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. To close your baffle, slide the left tab into the right slot until they snap together.
The mounting collar is as important as the baffle shield itself! An all metal(see image below) support collar with instructions is included. Ordinary baffles include substandard - and in some cases plastic collars. The collar must hold the baffle securely in place - and it must not be plastic. Plastic collars can and will be chewed through.
