Irwin Hanson STRAIT-LINE® Chalk Reels: Precision Layout for Every Job

When accurate layout lines are the difference between a clean build and a costly mistake, professionals reach for Irwin Hanson chalk reels. Under their trusted STRAIT-LINE® sub-brand, Irwin Hanson has developed one of the most complete and thoughtfully engineered line chalk reel lineups available, offering options that scale from trim carpenters to heavy-duty commercial framers.

A Lineup Built for Every Trade

A variety of reels are available with traditional or quick rewind, aluminum or ABS housings, large or extra-large chalk capacities, nested hook docks, extra-wide prong hooks, and anti-jam spools — so whether you're snapping lines on drywall or concrete, there's a STRAIT-LINE® reel engineered for the task.

• STRAIT-LINE® COMPACT: Features a convenient and compact design that makes it easy to store in a tool bag or tool box, perfect for finishing pros. A 3:1 gear ratio smoothly and quickly retracts the line, designed specifically to help professionals mark jobsites with speed and efficiency.
• STRAIT-LINE® SPEEDLINE™: Makes marking fast, rewinding faster, and chalk refilling easier, featuring a nested hook dock for compact storage without unwanted hook snagging and the ability to quickly hook and go with gloves on. The 100 ft. abrasion resistant poly line provides up to six strikes per pull.
• STRAIT-LINE® SPEEDLINE PRO™: Makes marking fast, rewinding faster, and chalk refilling easier, with a lightning fast 6:1 planetary gear ratio for rewinding 6X faster than traditional chalk line reels for fewer breaks. The 100 ft. hi-tensile line, robust steel handle, and large center hub deliver increased durability, strength, and torque, with durable ABS and rubber overmold housing for impact resistance.
• STRAIT-LINE® MACH6™ Aluminum: Features an easy fill and lock top for fast, clean refills and a lightning fast 6:1 planetary gear ratio for rewinding 6X faster than traditional chalk line reels. A nested hook dock allows for compact storage without unwanted hook snagging, with the ability to quickly hook and go with gloves on. The new spool design reduces line jamming, knotting, and fraying for reel longevity.
• STRAIT-LINE® LAYOUT PRO: Features large chalk capacity for fewer refills on large jobs, with a heavy-duty braided line that resists fraying and breaking over long distances.

What Sets Irwin Hanson STRAIT-LINE® Apart

Across the entire lineup, Irwin Hanson has focused on solving the real frustrations tradespeople face on the job: messy refills, snagging hooks, jammed spools, and slow rewinds. The STRAIT-LINE® Speedline™ features a fill door that is more than 70% larger than the previous design for quick and easy chalk fill. Meanwhile, the 100 ft. hi-tensile line, robust steel handle, and large center hub on the MACH6™ deliver increased durability, strength, and torque, with durable aluminum housing providing impact resistance. These are not gimmicks — they are thoughtful refinements that reduce downtime and keep layout work moving.
