These Trex boards were used to make a tiered outdoor shelf, but it eventually fell apart and all the kings horses and all the kings men could not put the boards back together again. They didn't try very hard, though. Anyone who's handy could reconstruct this homemade shelf. Need to clean up the yard and giving away for free! Four of the boards measure 3 feet, two are 3.5 feet and two are 30 inches.
