16 inch " solid " concrete block are extremely heavy and fairly immobile when just placed in a desired location ( not mortarred ) .........
the opening could be outlined with them ............
would give the dogs a visual to the opening ............
could be crawled over by humans....... if there was an emergency in the basement
" solid " concrete blocks are available in 4" ..... 8" ..... 12" ...... 16" sizes .......
16" are the biggest and heaviest ............. why i forementioned them
but a combination could be used .... with proper measuring
