Hello, I am looking for a constant force counter balance spring or springs that will support a sign board of approx. 25#. The travel for this support needs to be 30 inches min. I could use more than one spring in my design.
thanks, Bob

It's hard to suggest any hardware for custom projects, but you could consider our S140-25. See if this could work for you.
