Irwin IR64905ZR Chalk 8 Oz Fluorescent Orange

Product Description

The IRWIN IR64905ZR is a fluorescent orange chalk powder designed for use with chalk reel tools on job sites across multiple trades. Supplied in an 8-ounce container, this chalk produces high-visibility lines on a range of surfaces including concrete, wood, drywall, and roofing materials. The fluorescent orange color makes snapped lines easy to read in low-light conditions or on surfaces where standard blue or red chalk may be difficult to see. It is a consumable supply used by electricians, plumbers, framers, and general contractors during layout and marking tasks.

This chalk is suited for residential and commercial construction and renovation work. It is commonly used during rough-in layout, floor leveling, roofing, tile setting, and any task requiring straight reference lines over short or long distances. The 8-ounce size is appropriate for moderate-volume use on individual jobs or as a top-off supply for ongoing service work. Minimum order quantity from the supplier is 6 units per order.

Installation Notes

Chalk reels are a hand-tool consumable requiring no power source or code compliance beyond standard job-site safety practices. Fill the chalk reel reservoir per the reel manufacturer instructions, avoiding overfilling to prevent clumping. Keep chalk dry and sealed when not in use, as moisture will cause the powder to harden and clog the reel. Dispose of excess chalk per local environmental guidelines.
