This handy little tool is the first ever on the market to accurately show the layout for grommet placement, for Cirkit and Miniature House fixtures. Easy to use for tapewire layouts and takes the guess work out of wiring issues. Simply set the short section against the floor, put your pencil in the corner of the "L" and slide it around the room.
Line your tapewire just below the pencil mark. Remember keep the copper stripe up for horizontal lines, and to the left for vertical runs. Easy peasy!
