National Signal continues to innovate with the addition of our mid-size ‘full matrix’ message sign.

The SR490 combines the features of our large and small signs into a convenient package that delivers great legibility in a compact easy to use package. Available in manual lift or optional hydraulic lift.

With our newly positioned control there is no more kneeling or bending over to program your message.

And now, you can see your message while you program. No more walking around the sign.
