Method for restraining transverse movement of the lower edges of vertically hung sliding doors

A method for guiding the lower side edges of a pair of vertically hung horizontally spaced doors supported for sliding movement in directions generally parallel to the plane of the doors to prevent excessive movement of the lower side edges in directions transverse to their direction of travel, said method comprising, providing at selected locations adjacent the inner and outer lower side edges of the doors a nail-like guide pin having a lower end configured to be forcibly driven into and fixedly secured to the floor and an upper end bearing an enlarged portion having surfaces for slidingly engaging the lower side edges of the door, forcibly driving into the floor adjacent the lower side edges of the door said nail-like guide pin, said upper end of said nail-like guide pin having a vertical height less than the distance between said floor and a lower bottom edge of said door such that said door may be pivoted sideways to clear the pin and enable other pins to be driven into the floor, and securing to the upper end of the pin after it has been driven into the floor a cap comprising said enlarged portion having outer surfaces configured to slidingly abut a lower side edge surface of the associated door, said cap being removable to enable removal of the doors.
