What does the Corriveau winter support post do, and do I still need to clear snow?

The post is an adjustable steel post. A rotary screw sets its height from 78 to 118 in. (199 to 300 cm). It adds support to the structure of the gazebo, which gives you more time before you need to clear snow from the roof.

You still need to clear the snow. The warranty does not cover a frame that collapses under snow build-up.
