These are extremely finely finished panels. The openings come in 4x4 and 5x5. The 4x4 work out to a max height of 5’ and the 5x5 max at 6’. All wood is sanded and edged also each panel takes 58 pieces which are all pre-sealed. I do not use a roller on the wood rather rub on rub off. So it’s washed on. That way no product can disengage from the wood. And all small pieces are dip vatted. They do take longer to create and all work is done on site for custom fit. They are a true Tom Sawyer fence made to last generations. Drop me a line for a quote.
