A channel letter raceway does two main jobs. It houses the electrical components, including power supplies, wiring, and fasteners, and it lets installers mount a full set of letters as one unit instead of hanging each letter individually.
Excellart Sign Products offers three channel letter raceway options: Slim, Five, and Seven. Each raceway serves the same basic purpose. The difference is how much interior room the job needs for the power supply, wiring, service access, and mounting hardware.
Start With What Needs to Fit Inside
Before choosing a raceway size, start with the electrical and installation requirements.
Look at the size of the letters, the power supply, the wiring layout, and the amount of room the installer needs to work inside the raceway. Bigger letters and longer wiring runs usually need more interior space. Smaller modern power supplies may allow for a lower-profile raceway.
The goal is to choose the smallest raceway that still gives the job enough room to install, wire, and service correctly.
Built as a Raceway System
Every ESP channel letter raceway is extruded from domestically sourced 6063-T6 architectural-grade aluminum, the same material standard ESP uses across its frame products.
Each raceway is built as a two-piece system with a raceway body and a hinged lid. The lid opens for access to electrical components and fasteners, while helping shed water away from the interior.
The system also includes size-specific end caps and a brace. The brace fastens the raceway to the building and can also splice sections together when a run is longer than a single length. Together, those pieces help keep the letters grouped as one clean assembly from the bench to the wall.
CLRW Slim: A Low-Profile Raceway
CLRW Slim is the narrowest raceway option, measuring roughly 5” tall by 3” wide.
Slim was designed around modern power supplies, which have gotten smaller over time. When the power supply and wiring fit within a tighter footprint, Slim keeps the raceway lower profile while still letting the installer mount the letters as one unit.
Slim is the right place to start when the project does not need the extra interior space of the Five or Seven.
CLRW Five: More Width and Working Room
CLRW Five measures 5-1/4” tall by 5” wide.
The full 5” width gives installers more room for wiring, service access, and hardware. Compared to Slim, Five creates more interior working space without stepping up to the taller Seven profile.
For many channel letter projects, Five is the middle-ground option: more room than Slim, less height than Seven.
CLRW Seven: The Most Interior Space
CLRW Seven is the tallest raceway option, measuring 7-1/2” tall by 5” wide.
Seven is the better fit when the project needs the most working room inside the raceway. That may include larger letter sets, heavier wiring runs, or installs where service access and future hardware space matter.
On larger or more wiring-heavy jobs, the extra interior room can make installation and service easier.
