Who we are

Form Extender is a product line of American Tool Company located in Rochester MN, a family owned business founded by 3 generations of concrete contractors and finishers dating back to the early 1970’s.

Driven by the constant need to improve efficiency and reduce waste, we grew frustrated with the time and effort spent cutting lumber for form setting. This challenge sparked the creation of the Form Extender, a solution born out of desire to simplify the process and save valuable time and money on the job.

We’re thrilled to share this product with the rest of the industry! After extensive testing, refining, and using it on our own jobs, we’ve put in the time to perfect it. Now, it’s ready for contractors like you to benefit from.

Whether you are pouring foundations for large commercial jobs or doing residential driveways, patios, or sidewalks, our tools give you the versatility and confidence to tackle any job with ease. Every Form Extender we make is made right here in the USA built with tough 18 gauge galvanized steel.
