This CRL Extra Depth Aluminum Upper Channel is a universal double channel that provides extra depth, which allows sliding panels to be lifted into the track to be placed on bottom rails. The D613 Upper Channel may be used as top, bottom or side channel.

CRL Aluminum Extrusions and Accessories allow you to customize track assemblies to your individual needs. Made from the highest quality, No. 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.
