The STRANCO SB4-W is a single-character vinyl letter label printed with the letter W in black on a yellow background. Constructed from pressure sensitive vinyl coated cloth, this label measures 0.875 inches wide in a rectangular format. The removable adhesive backing allows placement and repositioning without leaving residue, making it a practical choice for temporary identification tasks. Licensed tradespeople and facility maintenance personnel use these labels for panel identification, circuit labeling, equipment tagging, and zone marking where clear, high-visibility character legibility is required.
This label is rated for indoor use and is suited for light industrial, commercial, and residential applications where clear alphanumeric identification is needed. Common installation scenarios include electrical panel directories, junction box identification, HVAC zone labeling, and plumbing system tagging. The high-visibility black-on-yellow color scheme meets common safety and identification standards for legibility in low-contrast environments.
Designed as a general-purpose indoor letter label for use on panels, equipment enclosures, conduit, ductwork, and other flat or lightly curved surfaces requiring alphanumeric identification.
Clean and dry the target surface before applying the label to ensure proper adhesion. Removable adhesive is not intended for permanent outdoor or high-moisture environments. No special tools are required for application. For electrical panel labeling, de-energize the panel per NEC guidelines before performing any interior identification work.
