Keson’s giant chalk line boxes are made in the USA, and they got their name for a few different reasons. Not only do the strings leave huge chalk lines, but their capacity allows users to make dozens of strikes with one box filling. They come with a big mouth fill with a rubber stopper that keeps the area shut. The Little Giant and Giant models have a standard 1:1 rewind, durable housing, and a grip handle. The Little Giant comes with either a 100-foot or 110-foot chalk line, while the Giant model has either a 130-foot or 150-foot chalk line. The G3X Giant has a 2:1 rewind, which allows for faster retrieval. And with an ergonomic design, it can reduce strain while using it.


Keson’s marking chalk is made in the USA, and it comes in five different variations. Standard chalk can be easily removed, and it can be used in interior or exterior applications. High-visibility chalk is great for high-contrast needs (such as dark surfaces), and they can be washed away after a few hours. Semi-permanent chalk is good for water-resistant applications and for chalk lines that need to be visible for longer periods of time. Permanent chalk is great for creating waterproof and weatherproof lines that need to be around for a while, which is useful for working in more extreme conditions or long-term applications. Ultimate dye chalk is meant to be laid down once, and it’s great for chalk line applications that will be covered or completely out of sight.

Can chalk boxes be used on the ground?

As long as the line is taut and both ends are close to being on the same plane, you can use a chalk box to mark any surface that is relatively flat. Once the string has been snapped, it will mark every point that it touches on or near that plane. Chalk lines can also be used on surfaces that are irregular or have holes (such as unfinished stud walls).

Where can I buy quality chalk boxes?

No contractor should live without a quality chalk box. And at Engineer Supply, we have some of the best on the market. We work with top-rated manufacturers with strong reputations in the industry, so you can be sure to get a chalk box that’s built to last. Feel free to look at what we have in stock, so you can find a tool that will meet your specific needs.

What's the best way to draw straight chalk lines?

As long as the string is taut, you can use a chalk box to snap a straight line. But if you go beyond 16 feet, it’s more difficult to get the string tight enough to snap an accurate line. The trick to marking longer chalk lines is to double-snap the string, which you can do by performing the following steps:
  • Stretch the string tight before tying it off.
  • Move to the midpoint of the string, and hold it down with your thumb.
  • Snap one side of the string to mark the first half of the line.
  • Snap the other side of the string to complete the line.
If you’re looking for a place where you can buy a chalk box that will last through years of use, be sure to look at what we have at Engineer Supply.
