These steel shelling are from Lowes and are identical to Home Depot.
Lot consists of 4 4 foot X 16 foot tall steel sections and 8- 8 foot long cross bars.
I was planning on bolting the two 4 x 8 X 16 together to make a 8 X 8 X16 foot tall tower.
Putting the floor at 9 1/2 feet high and ceiling at 16 foot (the top) OR put the floor at whatever hight and drop
a ready made blind on the frame.
This is heavy duty material and I see them at the store holding thousands of pounds.
I also have a couple 8 footers that could be used for a porch
$600 .00 cash also can deliver to DFW area for $100.00
Only selling because I'm 70 YRS old and do not do heights well any more.
