Panduit Vertical Cable Management D-rings provide a labor-saving solution for containing cables in a vertical pathway. The CMVDR2S model is designed for standard communication racks and features a flexible arm that allows for the insertion of complete cable bundles. Constructed from durable black polycarbonate, these D-rings offer a one-piece design for ease of installation and maintenance. They are ideal for use in conjunction with horizontal D-rings to create a complete open access solution on rack systems, and can also be mounted onto walls or other flat surfaces.
