Abstract: One embodiment is an L-shaped bracket which is a one-piece device formed from sheet metal and having two flat plate portions which are perpendicular to each other and meet at a juncture line. Each plate portion, secured to a panel, has an elongated through-hole with the hole in one plate portion being perpendicular to the juncture line, i.e., vertical; and the hole in the other plate portion being parallel to the juncture line. Screws, or other fastening means, extend through the elongated holes and the bracket and panel are adjusted along the length of the elongated holes and then the screws, or other fastener means, are fully tightened down to hold the bracket and panel in their adjusted positions. In another embodiment the bracket is F-shaped to grasp a panel between parallel plate portions.
