This is a magnetic version of a PVC clip for Pixel RGB Christmas lights. to minimize what is left on the house after the Christmas lights are taken down. All that is left on the house is a 4mm thick rare earth magnet that can be painted the color of the house.
It's designed to work with 1/2 inch Schedule 40 PVC pipe.
Here is where I bought the magnets: http://www.ebay.com/itm/201685899511
