Description
Southwire HB3AX48 Crossbar with HBFB Tray Clamps – Flexibility with Structural Advantage Southwire’s HB3AX48 Crossbar and Tray Clamps offer a fast, secure, and highly effective solution for mounting box rollers like the HB1A-9 and HB9A to cable trays. Unlike other cable tray roller systems that attach rollers to weaker cross rungs, this setup secures directly to the tray’s side rails—its strongest structural point—enhancing stability. The 48" crossbar not only supports the rollers but also adds beneficial stiffness to the tray itself, reinforcing the overall system. HBFB Tray Clamps can be mounted upright or inverted, allowing the crossbar to be positioned above or beneath the tray for maximum flexibility. With tool-free installation, a threaded “T” handle for 4" to 6" depth adjustment, and stainless steel tethered pins, the HB3AX48 Crossbar with HBFB Tray Clamps system is the superior choice.
