Milwaukee Chalk Line 45m Spool – Metal Crank, Planetary Gear, Anti-Jam

Where ordinary chalk lines struggle with snags and slow rewinds, this Milwaukee 45 m spool brings a 6:1 planetary gear system and a foldable metal crank for fast, controlled line retrieval. The reinforced housing shrugs off drops, while the large fill port and anti-jamming clutch keep you marking instead of fiddling.

Highlights

• 45 m braided nylon line for long, straight layout marks
• 6:1 planetary gear ratio delivers quick, smooth rewinding
• Foldable metal crank handle stores compactly and withstands heavy use
• Reinforced housing with impact resistance for jobsite durability
• Large chalk fill port speeds up refills and reduces spillage
• Anti-jamming clutch mechanism prevents line snags during retraction
• Integrated metal hook storage keeps the hook secure when not in use

In daily use

Load the spool with your preferred chalk (not included), snap a line for framing, flooring, or drywall layout, and reel it back in with minimal effort. The metal hook grabs edges firmly, and the foldable crank tucks away when you move to the next task. The planetary gear system means fewer wrist turns per retraction, so you can mark repeatedly without fatigue.
