Southwire 65104001, Open-Top Box Roller w/48" Crossbar And Two HBFB Clamps

Speed & Stability Combine with Southwire’s Open-Top Box Roller and HB3AX48 Mounting System Get cables in and out faster than ever with Southwire’s lightweight open-top box roller—engineered for speed, strength, and versatility. Its open-top design makes rope insertion and cable removal effortless, especially along straight runs or over outside vertical risers. The one-piece, high-strength die-cast aluminum frame delivers exceptional durability without added weight. Install the roller above or inside the tray using the HB3AX48 Crossbar which, unlike systems that attach to weaker cross rungs, this setup anchors directly to the tray’s side rails—its strongest structural point—enhancing stability and reinforcing the tray itself.
