thanks, I ordered them form ebay. about $4 for a set of 2 so I ordered 5 sets to have a few backups plus I'm still waitig for a corner ledge and a play ledge. wish I had the meas to make my own. one day maybe. I did habe to go to lowes and get new screws and wingnuts becayse tese ledges just came with regular screws. that would be a pain in the ass to clean and move every time, wingnuts, not so much.
