Southwire odr-250 D Ring Open Style Distribution Ring

Product Description

The SOUTHWIRE odr-250 is an open-style D ring distribution ring designed to support cables that must remain accessible after installation. Also called open D rings or backboard D rings, these fittings feature a smooth interior surface that protects cable jackets and insulation from abrasion during routing and over the life of the installation. Constructed from die cast aluminum, the odr-250 provides lasting durability in panel, rack, and backboard applications. Electricians and low-voltage technicians install these rings wherever organized, accessible cable management is required.

The odr-250 is used in electrical panels, telecom backboards, server rooms, and other enclosures where cables must be routed, bundled, and kept reachable for future service or adds. The open drop-in design allows cables to be inserted or removed without threading, making it a practical choice for installations that require frequent moves, adds, or changes. The 2.5-inch size accommodates larger cable bundles common in commercial and industrial wiring environments.

Installation Notes

Installation is typically performed by licensed electricians or low-voltage technicians. De-energize any circuits in the work area before mounting rings or routing cables. The open drop-in design allows cables to be seated without tools, though a screwdriver or drill may be needed to fasten the ring to the backboard. Follow applicable NEC guidelines for cable support spacing and bend radius when positioning rings.
