All materials expand and contract due to temperature changes, including cable tray systems. Understanding where and how often to allow for thermal expansion and contraction is an essential measurement to ensure the longevity of a cable tray system.

Cable tray system designs that do NOT take this into consideration will likely experience reduced performance and possible system failure.

Advantage of B-Line series heavy duty expansion plates

Eaton’s B-Line series heavy duty expansion splice plates are engineered to eliminate the NEMA recommended additional supports at each expansion joint where expansion splice plates are utilized.

Traditional expansion splices require the installation of two supports, one on either side of the expansion splice.

By utilizing B-Line’s heavy-duty expansion splice plate, no additional support is required when the splice is placed at quarter span. And B-Line’s thermal gap window simplifies gap setting during installation.
