CRL Plastic Lined Aluminum Upper Channel reduces noise and permits smooth movement of doors. The extra depth makes placement of sliding panels on bottom rails easier.

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.
