Back Aluminum plate that supports neon and has mounting holes & electrical penetrations cut into it using computer equipment. Electronic Display Board A programmable message board that uses LED (see definition below) light modules to produce displays and graphics. Also called Digital Message Boards, they can be programmed using a PC (personal computer) that is either hard wired to the sign or remote located via a modem.

Aluminum letters can be painted, drilled, have their backs tapped, and mounted to any surface using threaded studs and silicone adhesive. Plexiglass Face 3/16” thick, pigmented translucent plastic. Pylon Sign A sign, usually pole mounted, that is at least 10’ in overall height. Raceway A Rigid aluminum trough that conceals electrical components of signs and acts as a mounting bar to attach letters to building. Usually painted to match the wall it is mounted to. Readerboard A changeable message board that utilizes a font of letters and clear letter track to hold the letters in place. Return 5” deep aluminum side of sign that attaches letter face to back of sign. Transformer Electrical component designed to “step up” or “step down” voltages. Transformers are hi-voltage generating devices required to illuminate a neon sign. It can be concealed in raceways, inside of large letters, or in weatherproof boxes remotely located inside the building the sign containing the transformer is mounted to. Tube Support Glass or metal bracket used to hold neon tube off the back of a channel letter. Tube supports are mechanically fastened to the back of the letter.
