Basically a second version of the MindTrik Gutter Clip. This has a little extra room and will allow for 2 things. One, if you have 12mm nodes inserted into the PVC with wire behind the PVC. The clip has a little extra room to accommodate the wire behind the 1/2" PVC. Second, there is a 1/2" gap on the front that will allow strips to be fastened to the front of the PVC without the clip interfering.
