The STRANCO SB4-U is a single-character vinyl letter label printed with the letter U in black on a yellow background. It uses a removable pressure-sensitive adhesive, making it suitable for temporary identification, equipment marking, or job-site organization where repositioning is needed. The label measures 0.875 inches wide and is rectangular in format. Made from pressure-sensitive vinyl-coated cloth, it is intended for indoor use. Electricians, plumbers, HVAC techs, and general tradespeople use labels like this for panel identification, pipe marking, valve tagging, and component identification on the job.
This label is designed for indoor identification applications where a high-visibility single-character marker is needed. The yellow background with black lettering provides strong contrast for quick visual identification of equipment, panels, conduit runs, or valves. The removable adhesive allows the label to be repositioned or removed without leaving significant residue, which suits staging, temporary tagging, or situations where labeling may need to be updated after inspection.
Designed as a general-purpose indoor identification label compatible with smooth, clean surfaces on electrical panels, conduit, piping, valves, and equipment enclosures where removable adhesive letter marking is required.
Clean and dry the target surface before applying the label to ensure proper adhesion. Press firmly across the entire label surface to seat the adhesive. Because the adhesive is removable, avoid applying to rough or porous surfaces where adhesion may be reduced. No tools are required for application or removal.
