2x4s in a sheetrock matrix have a lot more strength than independent poles out in the air...

Breaking 4x4s is pretty impressive...must have been an unusual load vector...

Nice-looking product...would be nice for anchoring into a 4x4 or two 2s, but I wonder if the anchor screw spread might be too wide for both sets of screws to purchase into the "thin" face of a 2x4..
