The Pixel-Free LED Trim Mounting Channel is a fast and effective way to lay your Pixel-Free LED in straight lines, or mount to existing structures. Whether using for an architectural element, or retail/tradeshow display, this mounting channel goes up quickly and the corresponding Pixel-Free LED Trim product mounts firmly into place. Small grooves on the inside of the channel line up perfectly with the LED to provide a strong hold, even when mounted upside down. Select the correct size that corresponds to which Pixel-Free LED Trim product you have (4mm, 6mm, or 12mm products), and the desired length. Easily lay multiple sections together to form crisp straight lines over long runs.
