Milwaukee 48-22-3992 Chalk Line Kit 100 Ft Blue Fine Line

Product Description

The Milwaukee Electric Tool Corp 48-22-3992 is a 100-foot blue fine-line chalk line kit built for layout work on job sites. The reel uses a planetary gear system with a 6 to 1 gear retraction ratio, allowing fast, efficient line retrieval. A strip guard clutch protects the line during snapping to reduce breakage and extend service life. The flush handle storage design keeps the tool compact and ready to pocket or store in a tool bag. Rubber over-mold construction provides a secure grip in wet or dusty conditions. This kit is suited for carpenters, tile setters, framers, and other trades that require accurate, repeatable layout lines.

The 48-22-3992 is designed for straight-line layout applications on floors, walls, ceilings, and decking surfaces. The fine line chalk produces a narrow, precise mark, making it well suited for tile work, hardwood flooring, roofing, and framing layout where accuracy is critical. The blue chalk is highly visible on concrete, wood, and drywall substrates. The 100-foot capacity covers most standard residential and light commercial layout tasks without resetting the line.

Installation Notes

Chalk line reels require no power source and are used by carpenters, tile installers, roofers, and framers for layout marking. Fill the reel with chalk powder before first use and ensure the hook end is secured to a fixed reference point before pulling the line taut. Snap the line with a single, controlled motion perpendicular to the surface to produce a clean mark. Keep the reel dry when not in use to prevent chalk from caking inside the housing.
