History of Strait-Line Chalk Line Reel

The Strait-Line Company of Wilmington, Ohio, revolutionized the construction industry in the mid-20th century with their durable cast aluminum chalk line reels. Before these metal housings became standard, carpenters often used wooden spools. This specific teardrop design allowed the tool to function perfectly as a plumb bob when suspended, combining two essential layout tools into one.
