Whatever guy I took the time to get you a picture and told you what it is. If calling the plastic collar aluminum makes you feel better about your purchase and return, call it what you need to hopefully you find something that suits your needs
I meant no offense. In the picture it just looked like aluminum with a coating.
If it’s the plastic/composite like the cutting head is made from that the blades are mounted to…I’d think it add more support then a guy thinks….that stuff is pretty tuff.
Thank you for the picture.
