Pretty good mount but not quite as heavy duty as my older one from Channel Master

All four of the supplied mounting screws broke while attaching the mount to plywood using a variable speed drill, they broke after going about 1/4 inch into the wood.

Nice sturdy mount.

For my use it is a great mount

They are actually very solid and provide a secure mount for my weather station.

I later removed the fireplace and used this for HVAC ducting and the left over box on the roof used for the flue was and ideal mount for an antenna mast.

This mount worked out very well for mounting my digital tv yagi antenna
