Markal 80501 Temporary Chalk Marker Yellow Box of 144

Product Description

The MARKAL 80501 is a wide-format temporary chalk marker designed for fast, high-visibility marking across a broad range of trade surfaces. Each stick measures 4 inches long by 1 inch in diameter and lays down a bold yellow mark using a smooth, fine-texture chalk formula. The result is a richer color deposit than standard chalk, making marks easier to read in low-light or cluttered job-site conditions. This product is sold as a box of 144 individual chalk sticks, making it well suited for shop or site stocking. Trade professionals across HVAC, fabrication, plumbing, and general construction use chalk markers like this for layout lines, component labeling, and temporary identification on parts or assemblies before final installation.

The MARKAL 80501 is intended for temporary marking applications where the mark must be clearly visible but easy to remove after the job is complete. It performs on metals, woods, glass, ceramics, and rubber, covering the majority of surfaces encountered in mechanical, electrical, and general trade work. The fine-texture formula allows the chalk to glide smoothly across both rough and finished surfaces without dragging or skipping. With 7 colors available in the product family, job sites can use color-coding systems for phased work or multi-trade coordination. The yellow variant in this listing provides strong contrast against dark metals and unpainted substrates.

Installation Notes

Chalk markers of this type require no tools and no surface preparation for most applications. Marks are temporary and should be applied only to surfaces where removal is intended after inspection, layout, or assembly is complete. Store chalk sticks in a dry location to prevent moisture absorption, which can affect mark quality. No trade license is required for use, but follow any site-specific marking standards or inspection protocols when applying layout marks to structural or pressure-rated components.
