This would counter the weight at the one foot mark on the other side of the up-rite..
Then in reality you would be supported up to the 4 foot mark.
If a person were worried they could always use 3/4 EMT conduit or run a cable from the end of the top cross bar to the inside of the bottom cross bar.
This is a cantilever and is used in construction of buildings and bridges.
