Trimcap
Trimcap is a flexible plastic edging material used to finish and reinforce the faces of channel letters in illuminated signage fabrication. Commonly integrated into commercial sign production, trimcap secures acrylic faces to aluminum returns while providing a clean perimeter finish.
This material delivers structural retention by mechanically locking the sign face into the channel letter body. Engineered for flexibility and consistent fit, trimcap supports precise bending around letter shapes and curves while maintaining edge stability. The construction contributes to uniform light diffusion and finished appearance across illuminated sign assemblies in professional fabrication environments.
Compatible with acrylic sign faces and aluminum channel letter returns. Suitable for indoor and outdoor illuminated signage applications and commonly integrated into channel letter fabrication, face retention systems, and LED sign assembly workflows.
Common applications include front-lit channel letters, reverse-lit letter assemblies, cabinet sign faces, and custom illuminated branding elements. Ideal for commercial sign shops requiring secure face retention and a clean finished edge.
Available in multiple colors and sizes to meet project requirements.
