The expansion splice connector in black joins two 8" (203 mm), 12" (305 mm), 18" (457 mm), 24" (610 mm), or 30" (762 mm) wide Wyr-Grid® Pathways together in applications where small gaps between horizontal pathways prevent the use of standard WGSPL1218, WGSPL2430, WGESPL or WGESPL2430 Wyr-Grid® splice components. Each package comes with one expansion splice connector.
