Claim:
A grid simulating muntins, the grid comprising a first plurality of spaced elongated members connected to a second plurality of spaced elongated members, wherein one of the elongated members of the first plurality of spaced elongated members defined as the first elongated member comprises: a first side having a length, an outer surface, a first end and an opposite second end, the first side continuous along its length from the first end to the second end of the first side; a second side having a length, an outer surface, a first end and an opposite second end, the second side continuous along its length from the first end to the second end of the second side; a third side having a length and connected to the first and the second sides; a fourth side opposite the third side, the fourth side having a length and connected to the first and the second sides, wherein the length of the first side and the length of the second side are each greater than the length of the third side and the length of the fourth side; the first side, the second side, the third side and the fourth side are connected such that connected portions of the first side, the second side, the third side and the fourth side of the first elongated member (1) have the second side opposite to the first side; (2) have the outer surface of the second side facing away from the outer surface of the first side, and (3) have the first end of the first side and the first end of the second side adjacent to one another; the first side having a first end portion, the first end portion attached directly to the first end of the first side, and the second side having a second end portion, the second end portion attached directly to the first end of the second side, wherein the first end portion and the second end portion are spaced from one another, such that (a) the first end portion is movable in a first direction to position the first end portion over the outer surface of the first side and in an opposite second direction away from the outer surface of the first side, (b) the second end portion is moveable in a first direction over the outer surface of the second side and in an opposite second direction away from the outer surface of the second side, and (c) the first end portion and the second end portion are simultaneously moveable in their respective first direction; the first end portion and the second end portion each have a ledge, each said ledge having a first end connected to said first and second end portions, respectively, and a second end distal to said first end, said second end defining a groove configured to receive an extension that is substantially perpendicular to the first and second sides of said first elongated member, said distal end of said groove having a first member configured to rest on an upper surface of said extension, and a second member configured to abut a groove in said extension resulting in restricted movement of the first elongated member in the longitudinal direction of said extension.
