The SJ-77-W forms part of the INABA DENKO SLIMDUCT SD trunking system and provides a practical connection point between two SD-77 duct sections. A screw-fixed cover secures the coupler in place, with two stainless steel screws supplied for installation.
Its durable UV- and water-resistant PVC construction makes the white duct connector suitable for indoor and outdoor use.
