While perusing through the pictures of these wonderful heat registers, you may notice that it conveys different color tones. This particular vent is crafted in the dark oil rubbed bronze patina and imparts tones that have a coffee color to a dark gray and almost black color, depending on light conditions at the time. Screw holds on the vertical height side of these grilles is standard. You can request no holes for the floor grilles if you wish - just ask. Choose light oil rubbed bronze, dark oil rubbed bronze (shown), or burnished bronze. Please view the Turner Collection to see the additional finishes.
