Inlays, Inc., offers a line of Vinyl Stickon depth and safety markers (black characters on white). Vinyl Stickons are made of an industrial grade, skid-resistant vinyl material. They are a professional alternative when doing depth and safety marker renovations. Vinyl Stickons adhere to most deck surfaces, including existing tile, eliminating stenciling or other costly installations. Vinyl Stickons are for above water use only and should be installed using our installation kit. Stickons are available in 6″ x 6″ or 8″ x 8″ with four-inch or six-inch numbers and letters. They are centered vertically and horizontally. All Vinyl Stickons Are Skid Resistant.
