105GO ProChalk® Marking Chalk – High Visibility Glo‑Orange, 5 lb

The 105GO ProChalk® High Visibility Glo‑Orange Marking Chalk is a professional‑grade layout solution engineered for maximum visibility in demanding jobsite conditions. Packaged in a 5 lb bulk container, this high‑visibility chalk is designed for contractors and tradespeople who need bright, attention‑grabbing markings that stand out on dark, dusty, or low‑contrast surfaces.

The Glo‑Orange color delivers exceptional contrast, making snap lines easy to see in outdoor environments, low‑light conditions, or busy construction sites. This chalk formulation is ideal for temporary layout and alignment tasks where immediate visibility is critical for accuracy and efficiency. Its standard chalk composition allows markings to remain visible during active work while being removable over time.

Formulated for smooth flow and consistent line release, ProChalk® Glo‑Orange chalk is compatible with standard chalk reels and chalk lines. The fine powder texture minimizes clogging and supports clean, crisp snap lines. The 5 lb container is well suited for high‑volume use, helping reduce refill frequency and supporting cost‑efficient jobsite operations.
