CRL's Aluminum Plastic Lined Upper Channel provides all the advantages of plastic and aluminum tracks. Plastic lining assures silent and smooth door movement. Aluminum outer channel matches the color and dimensions of the assembly components.

CRL Aluminum Extrusions and Accessories allow you to customize track assemblies to your individual needs. Made from the highest quality number 6063 alloy - T-5 aluminum, our extrusions are uniformly anodized. Anodizing is the process of electronically adding a thicker coat of oxidizing to aluminum, which protects the metal from scratches, blemishes and atmosphere.
