AGL designs and manufactures some of the world's best construction laser levels. Their quality design and quality components build an extremely reliable and durable product. AGL has been in business for more than 40 years and developed and successfully built the first pipe laser that started the construction laser industry. The introduction of the pipe laser coincided with the mass production of the first hydraulic excavators. With these new products, pipe and trenching contractors had highly productive tools that allowed them to dig more ditch accurately and install more pipe in less time. This was a quantum leap in productivity for pipe contractors. To this day, AGL is committed to producing the most accurate and reliable laser level products for the construction industry.
