what more can i say than is in the title? we got this and attempted to insert 2x4s into the little holes. they were TOO SMALL. HUH? seriously landmann? you must not have lived on the land too long.... cause 'round here, 2x4s are a specific size.... and these little black tubes are about 1/8- 1/4" too small. yes, you can shave the ends of the boards to fit, but doesn't that defeat the purpose of this easy set up? we sent this back and got an all metal one. and the metal one WAS easy to set up. and it worked and will last a lot longer.
