The Irwin Strait-Line Classic chalk reel is the standard layout tool for snapping straight reference lines on framing, flooring, drywall, and concrete. This variant has the same cast aluminum housing as the standard model with a blue powder-coat finish - useful for tradespeople who color-code tools by chalk type (e.g., blue body = blue chalk) so the right reel is in hand without checking the refill door. The 100 ft abrasion-resistant poly line gives 5-6 sharp chalk strikes per pull before needing a re-fill.

• Blue powder-coated cast aluminum housing
• 100 ft abrasion-resistant poly line, 5-6 strikes per chalk fill
• Cast aluminum housing for impact resistance
• 1:1 gear ratio - one crank revolution per line revolution
• Robust steel handle with large center hub for fast winding
• Nested hook dock keeps the end hook flush with the housing for pocket carry
• Anti-jam spool design protects the line from kinks
• Wide refill door accepts any standard chalk bottle
• Doubles as a plumb bob for vertical layout

Tip: Pair this blue-body reel with BLUE chalk for general permanent layout (framing, flooring nail lines). Many crews keep a blue-body reel and a red-body reel side-by-side, color-matched to the chalk inside, to avoid mixing up reference lines.
