Keson Magnetic Box Beam Level

Level and plumb are two of the basics of construction and Keson has been at the craft since 1968 when Roy Nosek started the business out of his basement. There are substantive differences in their Keson Magnetic Box Beam Level – model LKB48M, most notably the Focus Vial by SOLA with 20% magnification and color contrast for easier reading of the bubble. Keson sent us one of their magnetic box beam levels recently, and we’re ready to level with you on our opinion of it.

Keson and SOLA – Not Leveling the Playing Field

Keson has been a family owned and operated business for three generations. When Keson partnered with SOLA, another three-generation family owned and operated business, they have definitely taken strides to ensure their playing field is not a level one.

As Aaron Nosek, Keson LLC President shared, in addition to the line of SOLA levels, “We are also very excited to capitalize on the SOLA’s long history of manufacturing and cutting-edge innovation to provide a more affordable version of high-quality levels under the Keson brand.”

Both companies bring a great deal to the partnership – the Focus Vial is clearly a positive even though our photo is a smidge out of focus!

A Sight for Sore Eyes – The SOLA Focus Vials are Enlightening

The merger between Keson and SOLA have partnered their manufacturing capabilities but also their innovative technologies. The Keson Magnetic Box Beam Level utilizes three SOLA Focus Vials that have a 20% magnification power. Another tremendous feature is the two color contrast that makes sighting in the bubble so much easier.

Notice the dark green ends, the dark outline around the bubble, and the wide viewing window. This is significantly easier to read – even with my aging eyes.

When compared to a more traditional level, I found the Keson Magnetic Box Beam Level is significantly easier to read from a far, from the top, as well as looking at the focus vials on the far ends.

A more traditional end vial shows a clear tube with a clear bubble and the traditional two thin lines to try to dial it in. Not quite the same visual ‘pop.’

Looking at these two levels from the top, the size of the viewing window and phenomenal contrast of the SOLA Focus Vial makes the Keson Magnetic Box Beam Level the clear winner.

A Magnetic Personality That’s Easy to Handle

The Keson Magnetic Box Beam Level has put that little bit extra into the ergonomics of this line of levels. It would be faster and cheaper to utilize a slot in the body but instead Keson added the two handholds and still kept the price down.

Two of the most comfortable hand holds I have ever experienced integrated into a level. Easy to hold, carry and use.

This works too. . . and this concludes the similarities between the two level’s handles.

Not all 48 inch magnetic levels are created equal. I own one of those ‘other’ brands. When I place my other 4 foot level on a metal pole or edge of a metal shelf, it immediately slides straight down to the floor. While it does stay magnetically attached to the metal, it gives in to our friend gravity. The Keson 4 foot level has SIX sets of magnets with the power to hold tightly exactly where you place it – even hanging upside down from a steel I-beam. Gravity, schmavity!

Here you can see all 6 sets of magnets cleanly embedded into the aluminum Keson Magnetic Box Beam Level.

The magnets are easily seen on the smoothly machined side of the aluminum box beam. The Keson Magnetic Box Beam Level feels solid and substantial when you are using it but actually weighs in at a svelte 3.4 lbs. The combination of the hand holds, aluminum body, and Focus Vials make this both a precise and sturdy tool for any work site.

Accuracy and basic info are printed right on the level

Whenever I am digging holes, pouring cement, and securing large, heavy posts, I find that my friends don’t return my calls as quickly. . .or at all. This makes the Keson Magnetic Box Beam Level the perfect tool to free up my hands while making sure that my posts are plum and true in all directions before the cement sets.

Keson Magnetic Box Beam Level
Look Mom, no hands! I can place the Keson level onto the side of this post and still have two hands free to work the cement and securing straps. It’s the “friends optional” feature!

Upon further inspection . . . I wish I had the Keson Magnetic Box Beam Level before I eyeballed this post in place. Take note of the firm hold the magnetic surface has on this painted pole.

Keson Magnetic Box Beam Level – Straight Forward Tools from Straight Forward People

The fact that Roy’s wife Evelyn suggested the name Keson based upon spelling their last name backwards speaks to some humility in their origins. They have worked as a family for 3 generations to create and innovate. They look to be continuing this family tradition with the new product line and the Keson Magnetic Box Beam Level. This is a high quality level at a very affordable price point.
