The other day I was working inside and noticed a guy outside installing a deck at a new home we are working at.....he was using a Dewalt screw gun and had an attachment on it that allowed him to set screws while standing and only using one hand to do so.....it wasn't an auto-feed type attachment it was ''manual"....he would load one 3" screw at a time and then set it.....then repeat....he was fast and I liked the fact that he didn't need special screws for it....this thing was nice....I didn't have a chance to ask him about it.....he finished the deck and is working out of state now.....i cant find it.....anyone know of this attachment???
