This is a stack cover originally designed for a diesel truck with 6" stacks to prevent rain and/or other debris from entering into exhaust stacks while the vehicle is not being used. There is a thread hole on the back side to allow any standard broom handle to screw into the cover and allow easy installation without the need of a ladder or climbing onto the vehicle or equipment. Can be easily scaled for other size exhaust stacks.

I have tested these printed from PLA and they have lasted 10-12 months outdoors in the elements without cracking.
