Are these Vintage series samples square edge or tongue and groove? The photos show both and the description says nothing. Thanks.

Hi Marty! I am so sorry for the confusion caused. We offer these boards in square shoulder (for use with top down/face fasteners) as well as grooved (for use with hidden clip fasteners). The samples are made out of the deck boards, themselves, so they are a mix of both square shouldered and grooved. There isn't a way to request one or the other as the sample, though. Please feel free to give us a call at 877.275.2935 if you have any questions or need further assistance! - TimberTech Support
