CLEAN-EDGE
ILLUMINATED LETTER SYSTEMS
Custom Trimless Channel Letters
Seamless Front-Lit Letters with Precision-Fit Acrylic Faces
Trimless channel letters eliminate the visible trim cap around the acrylic face, creating a cleaner and more refined illuminated appearance.
Available in multiple structural options, from exposed and flush acrylic face systems to precision-machined solid aluminum letters with straight or beveled edges.

What Makes Trimless Channel Letters Different?
A cleaner illuminated face with less visible edge interruption.
Traditional trim cap letters use an external edge strip to secure the acrylic face. Trimless channel letters remove the visible trim cap, creating a cleaner transition between the illuminated face and the letter body.
No Visible Trim Cap
A cleaner front-lit appearance with minimal visible edge framing.
Precision Fit
Acrylic and metal components are fabricated for accurate alignment and consistent edge quality.
Full Illuminated Face
The front surface remains visually open and continuous, creating a stronger illuminated appearance.
Modern Appearance
Well suited to retail, hospitality, interiors, and branded environments where clean detailing matters.
Designed for projects where edge detail matters as much as illumination.
