The media could not be loaded. These worked real well though it was necessary to shave the 4x4's a bit. I'm in the process of painting them to match the 4x4 paint.

LIght weight but solid. When anchored to the floor it will stop the post from slipping.

Much cheaper than box store prices, saved me a lot and looks great! You do have to shave down some of the 4x4’s to get them in but it’s not difficult. They worked well for building the railing on my deck!

Installed last summer and have already rusted. Very unhappy because they would be super difficult to remove and change out.
