The STRANCO SB4-S is a single-character vinyl letter label printed with the letter S on a high-visibility yellow background with black text. Constructed from pressure sensitive vinyl coated cloth, this label uses a removable adhesive that allows repositioning or clean removal without leaving residue. Measuring 0.875 inches wide in a rectangular format, it is suited for identification, circuit labeling, equipment marking, and panel organization tasks common in electrical, HVAC, plumbing, and industrial service work. Trade professionals use labels of this type to mark disconnect switches, junction boxes, valve handles, pipe runs, and control panels for fast visual identification.
This label is intended for indoor use and is part of a high-visibility numbering and lettering system. The yellow background with black legend provides strong contrast, making it readable at a glance in low-light mechanical rooms, electrical panels, and equipment closets. It is sold individually and ships with a minimum order quantity of one. Typical applications include service labeling during installation, replacement work, and preventive maintenance identification across residential and commercial trade environments.
Designed as a general-purpose single-character identification label for use on flat, smooth surfaces in indoor electrical, HVAC, plumbing, and industrial service applications where removable adhesive labeling is required.
Clean and dry the target surface before application to ensure proper adhesion. Apply firm pressure across the label face to seat the adhesive fully. Because this label uses a removable adhesive, avoid applying it to surfaces that may be exposed to moisture, oils, or extreme heat, which can reduce adhesion. No special tools are required for placement or removal.
