Universal Junction Box Cover Set

This versatile remix includes two base options and three cover sizes, providing flexibility to fit multiple junction box configurations. The bases are compatible with all covers, ensuring easy customization. However, the large base (50–102 mm c-c) is not recommended with the smallest cover (80 mm) since the base is wider than the cover.
