SWANSON BOX BEAM MAGNETIC LEVELS
The BBLM Series is defined by its heavy-duty aluminum frame. While cheaper "I-beam" levels can twist or bend under the weight of a heavy toolbox or a fall from a ladder, the box-beam construction provides a rigid, four-sided reinforced structure.
What truly sets this series apart, however, is the integration of industrial-strength rare earth magnets . Unlike standard magnetic levels that can slide or vibrate loose, these high-pull magnets ensure a relentless, "hands-free" grip on steel studs and pipes. This level of magnetism isn't just a convenience; it is a critical safety feature that ensures total accuracy on the most demanding jobsites.
Choosing a Swanson level is a nod to the past—an appreciation for the days when tools were built to be passed down—while embracing the material science of the present. It is the physical manifestation of the Swanson motto: "Always true. Always Swanson."
