Product Description

The HY-KO ST-3 is a stencil set designed for marking, labeling, and identification tasks across job sites, facilities, and utility applications. The set includes 3-inch characters made from heavy-duty stencil board, offering a reusable and flexible format that holds up to repeated use. The material is water-resistant, making it suitable for both indoor and outdoor marking applications. Tradespeople, facilities maintenance crews, and contractors use stencil sets like this one for pipe labeling, equipment identification, address marking, and other field-lettering tasks where clean, legible characters are required.

This set is well-suited for use in plumbing, electrical, HVAC, and general construction environments where standardized labeling is part of code compliance or site organization. The 3-inch character size is a common choice for utility and facility marking where characters need to be legible at a short reading distance.
