1.) Built-in Track on Backside of Metal Frames [Matte Black and Silver] (Standard): --
The profile of Metal frame we use has a built-in track on the backside of the frame. We believe this track is the best way to hang these pieces ESPECIALLY when you want your pieces to hang side by side by side. The track is a fixed distance down from the top-line of the picture frame. Which makes it easy to hang these pieces on the same line as the other pictures in your order. We suggest setting two-screws along a straight line from 7 to 12-inches apart (depending on your framed size). This also allows the pieces to slide left to right without tilting so that you'll be able to distribute the spacing between pieces evenly.
