The C.H. HANSON 10190 is a 138-piece PVC plastic stencil set designed for marking letters and numbers on job sites, equipment, piping, and surfaces that require clear, durable identification. Each character stands 2 inches tall, making the markings readable at a practical working distance. The interlocking corner design keeps individual stencils aligned during use, reducing drift and improving consistency across repeated markings. This set is suited for use by HVAC technicians, plumbers, electricians, pipefitters, and general contractors who need a reliable, reusable marking solution for both field and shop environments.
The 10190 stencil set is commonly used in commercial and residential trade applications where permanent or semi-permanent surface labeling is required. Typical uses include pipe identification, equipment tagging, floor marking, and panel labeling. The PVC material holds up to common marking fluids and light solvents, making it practical across a range of substrates including metal, concrete, wood, and painted surfaces.
Designed as a general-purpose number and letter stencil set suitable for use across trade industries including HVAC, plumbing, electrical, and construction for surface identification and labeling tasks.
No specialized tools are required to use this stencil set. Secure each stencil firmly against the target surface before applying marking fluid to prevent bleeding or smearing. Allow markings to dry fully before removing stencils to preserve edge definition. Clean stencils promptly after use to extend service life and prevent buildup of marking material.
