Depending on the number of curtain rod applications, types of wood curtain rod brackets include single brackets and double brackets. As for the mounting surface, wood curtain rod brackets are classified as ceiling brackets, wall-mount brackets and inside-mount socket brackets.
While single curtain rod brackets are common and come in many shapes and designs, double brackets are made to allow two curtain poles to fit one window. Usually, the front position is bigger to fit the large rod for the main curtains, and the thinner diameter at the back fits the smaller rod with the lightweight drapes, sheers or nets.
Wall-mount brackets are suitable for installing the curtain outside the window recess. As they are easily exposed, they sometimes play as decorative items, like curtain rod sconce brackets. Moreover, wall-mount brackets allow for curtain return, which creates a neat look. If there is limited wall space, an inside-mount socket bracket is a good solution because it can be installed inside the window recess and eliminates the need of finials.
Compared to wall-mount brackets and inside-mount socket brackets, ceiling brackets are more flexible, as they can be fixed to the wall, ceiling or top of a window recess. They usually have short projections to reduce the light gap above the curtain.
