If any of you have had this Afmat product you have had my issue where you store the attachment under the blower in front of the trigger WOW what a mess. This allows you to simply put your attachment on top of the entire blower out of your way and not worry about having to take it off each time or choose only the one that does not have the brushes since it will not stand upright with that attachment. Just super glue or epoxy ( I used super glue worked just fine).
This may work on other blowers attachments with an approx OD of 13.8 mm. I'm sure you could increase or decrease depending on your device with trial and error.
