For those of you looking for a very inexpensive baffle we are offering the wraparound SB8GLV with plain electro galvanized finish! This is the least expensive product on the market that actually works *Fully galvanized and will not rust* 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 locking tab may be bent to secure the seam. This is important as raccoons have learned how to pop ordinary baffles open.
