Magnetic Clips for C7 and C9 Christmas Lights
These magnetic clips are an elegant solution to installing traditional C7 and C9 Christmas light cords on metal roofs and along metal flashing.
Simple installation instructions: Simply snap a clip on every socket of a Christmas light cord constructed with 18 AWG wire. Be sure to choose SPT-1 or SPT-2 specified clips based on your cord's insulation specification.
Test your surface with a common household magnet to confirm that a magnet will have a strong hold.
