Similar to the Cambridge solar post cap's low-profile design, the Oxford model is crafted from durable, weather-resistant cast aluminum and finished with a robust powder coat satin available in three colors. It features a unique decorative glass lens and two surface mount LEDs. The 6x6 Oxford Solar Post Cap casts a warm, natural glow, automatically illuminating at dusk to beautifully enhance your fence, porch, or deck. This superior design by Classy Caps includes an adaptor to accommodate three post sizes: an actual 6"x6", 5.5"x5.5", or 5"x5" post.
