Some products are better illustrated with video. When I came across the Stringa-Level web site, I found this: “The system is comprised of interlocking sections with level vials that are used in series to form a continuous angle support shelf on which the first course of tile rests.” Come again? I didn’t develop an appreciation for this product until I saw the video. If you are in the business of installing tile, this might be the product for you. The pieces in Stringa-Level lock together to form a level line that will support the installation of tile around corners and above the floor. It’s difficult to explain, so watch the video.
