Rah, is that a 2' tall model pictured? I see they make sizes 2' to 6' but can also make custom sizes.
I need to get one of those rat guards. I periodically have muskrats use the overflows to travel from creek to pond and from pond to pond. If they were prevented from using the protected pathways of the overflow tubes it would force them to get above ground and the red tail hawks have access to them. Which would save me having to trap them.
