The Speedline Pro chalk reel uses a 6:1 planetary gear ratio that rewinds line six times faster than a traditional 1:1 reel, so you spend less time cranking between snaps. Lightweight ABS housing with rubber overmold grip absorbs job-site impacts and stays comfortable on long layout runs.

• 6:1 planetary gear ratio for fast line rewind
• 100 Ft of hi-tensile braided nylon/polyester line
• Durable ABS housing with rubber overmold grip
• Wide prong hook for secure anchoring on framing and slabs
• Robust steel handle holds up to heavy daily use
• 1/4-turn locking top for quick chalk refills (locks in chalk between jobs)
• Anti-jam spool design reduces line damage and twist
• Fishing-reel-style knob for smooth, controlled retraction
• Reel only - chalk sold separately (Irwin 65101 blue or 65102 red)

Tip: Pair with Irwin Strait-Line Permanent (red) chalk for layout that needs to survive weather, or Standard (blue) chalk for interior work where the line should brush off after the cut. For best snap, pull the line just enough to lift it 6" to 12" off the surface, then release straight down.
