Neon is the illumination source for all open face channel letter signs, and the neon is actually exposed instead of being encased behind colored acrylic. The face of this letter is typically open, but an optional clear acrylic face is also available.
An open face letter return (side) is 3" instead of the usual 5". This gives the neon illumination full exposure and ensures the sign can be easily read.
NOTE: Direct Sign Wholesale no longer produces neon illumination, but is capable of producing open face channel letter cans for customers who want to install their own neon.
