Irwin IR66405 White Marking Crayon

Product Description

The IRWIN IR66405 is a white marking crayon designed for fast, legible marks on rough and irregular surfaces commonly encountered in trade work. Marking crayons of this type leave bold, visible lines on concrete, masonry, lumber, pipe, and metal — surfaces where pencils skip and chalk dusts away. This crayon is sold individually and is a standard layout and identification tool used by electricians, plumbers, pipefitters, ironworkers, and general contractors during rough-in, fabrication, and inspection stages.

White marking crayons are used across residential and commercial job sites where high-contrast marking is needed on dark or porous substrates. Common applications include marking cut lines on black iron pipe, labeling concrete block, indicating measurements on rough lumber, and flagging inspection points on structural steel. The white color provides visibility on surfaces where standard graphite or dark crayons would be difficult to read.

Key Features

• White color provides high contrast on dark, rough, or porous surfaces
• Formulated to mark on concrete, masonry, pipe, lumber, and steel
• Crayon format resists crumbling better than chalk on irregular surfaces
• Compact size fits in a tool belt, apron pocket, or layout bag
• Sold individually — minimum order quantity of 12 units per purchase

Compatibility

Designed as a standard marking crayon suitable for general trade use on construction and industrial job sites where surface marking on rough or non-porous materials is required.

Installation Notes

Marking crayons require no tools for use and no special handling precautions beyond standard job site practices. On surfaces that will be painted or coated, verify that crayon marks are compatible with the finish system or remove marks prior to coating. Store crayons away from excessive heat to prevent softening.
