Southwire dst-300 Aluminum D Ring Cable Support 3 Inch

Product Description

The SOUTHWIRE dst-300 is an aluminum D ring designed to support and organize multiple cable runs on walls, ceilings, and communication backboards. With a 3-inch inside diameter, it provides ample space to route vertical or horizontal cable bundles without sharp bends or contact stress. The smooth non-conductive aluminum surface protects cable jackets from abrasion during installation and over the life of the run. Licensed electricians, low-voltage technicians, and structured-cabling installers use this type of ring to keep data, voice, and control wiring sorted and properly supported at regular intervals.

The dst-300 is suited for commercial and residential structured-cabling applications, including telecom backboards, network equipment racks, wall-mounted cable ladders, and communication room installations. It is commonly used to dress horizontal and vertical cable bundles along flat surfaces, keeping runs tidy and accessible for future moves, adds, and changes. The aluminum construction makes it a practical choice for installations that require a lightweight, rigid support with a non-conductive surface.

Key Features

• 3-inch inside diameter accommodates high-density cable bundles in vertical or horizontal runs
• Smooth non-conductive aluminum surface prevents cable jacket damage
• Lightweight, high-strength aluminum construction for long-term durability
• Mounts to walls, ceilings, backboards, and flat surfaces
• Suitable for organizing data, voice, and low-voltage control cabling

Compatibility

Designed as an OEM-style cable management fitting for use in structured-cabling, telecommunications backboard, and rack-and-panel installations requiring D ring cable supports with a 3-inch inside diameter.

Installation Notes

Installation is typically performed by licensed electricians or registered communications distribution designers (RCDDs) following TIA-568 cabling standards and applicable local codes. Secure the ring to the mounting surface before routing cables to avoid overstressing fasteners. Do not exceed the fill capacity of the ring, and avoid sharp tie-wrap tension directly against cable jackets. Verify that all power circuits in the work area are de-energized before beginning any cable routing work in energized panels or enclosures.
