​This item in the image is a type of extruded H-bar or connector profile, typically made of aluminum, which is a common component in the sign industry for joining panels.

This profile is primarily used to connect flat sign panels when a sign face is larger than available material, or for modular designs:
  • Joining Sign Faces: The H-shape extrusion is designed to hold the edges (flanges) of two sign face panels, creating a clean, seamless joint. This is especially useful for large sign cabinets or billboards.
  • Sign Cabinet Construction: It integrates into the overall structure of a sign, providing support and a method for assembly.
  • Modular Displays: This type of connector can be used in modular or changeable sign systems, where panels need to be inserted, removed, or replaced easily.
  • Aesthetic Finish: It provides a professional, finished look to the edge where two panels meet, concealing any raw edges of the sign material. 
  • The use of aluminum ensures the component is durable and corrosion-resistant for both indoor and outdoor signage applications.
