Keson Chalk Line Reel G100 100 Foot 12 Ounce Capacity Little Giant (1/8 Inch Bold Braided String ABS Case Steel Crank Concrete Marking Layout)

Keson G100 Little Giant 100-Foot High-Capacity Chalk Line Reel

The Keson G100 Little Giant is a 100-foot heavy-duty chalk line reel engineered with a 12-ounce chalk reservoir capacity and a 1/8-inch thick braided loose-woven polyester string for snapping ultra-bold layout lines across asphalt, rough concrete, and structural steel. Built with a high-impact ABS plastic housing and a single-piece steel rewind crank arm operating on a 1:1 drive gear ratio, this continuous layout tool holds nearly three times the chalk payload of standard reels to eliminate frequent refilling delays. Equipped with a wide BigMouth filler port featuring a leak-resistant rubber stopper and an oversized shovel-style gloved grip, it gives commercial concrete contractors, road crews, and framers maximum visibility during outdoor layout work.

Best Used For:

• Asphalt Paving & Parking Lot Striping Layout: Snapping thick 1/8-inch high-visibility chalk lines across rough asphalt and roadway surfaces prior to paint application.
• Commercial Building Concrete Foundation Slab Marking: Striking long-run structural wall boundaries and anchor bolt reference grids across rough cured concrete floors.
• Roofing & Exterior Decking Installation: Marking straight chalk guidelines across extended plywood roof sheathing, timber joists, and corrugated metal decking panels.

Key Performance & Safety Features

• One-Piece Steel Rewind Crank: Solid steel crank handle provides smooth line retrieval and features a recessed clasp for compact storage.
• BigMouth Fast-Fill Port: Oversized fill opening allows quick, spill-free chalk loading and seals tightly with a leak-proof stopper.

Technical Specifications

Pro-Tip: Give the reel housing a gentle shake while pulling out string to ensure the thick 1/8-inch polyester line coats evenly with chalk powder before snapping long layout lines.
