This baffle fit our Wild Birds Unlimited Pole system with no problem. We have had it installed for almost a year, and have seen a lot of squirrels climb the pole and then back down in disappointment when they can't find a way around or over it.
I gave it 4 stars instead of 5 because we haven't been able to make it hang straight, which bothers me a lot. If there is something we need to know to accomplish that, input would be greatly appreciated. Otherwise, this is an amazing, well made product.

Erva Comments: Thanks for the review. I suspect it's not straight on your pole because it's not resting on the flat side of the mounting collar. The dual purpose collar (designed for use with your SB6 Disk style baffle - and also our cone shapped baffles - necessitates that the flat side of the bracket is mounted in the up position - for the disk style baffles. Please check the bracket - or refer to the descriptive image found in the SB6 product description. Please let us know if this solves the problem.
