Can Sillites be installed with “picture frame” type windows without a conventional stool?
Yes – So long as the bottom shelf is 2-1/4″ or wider, the SCR will drop into a 1-3/4″ diameter hole and extend into the wall cavity. Note that if the window is centered over a stud in the wall, the electrician simply drills a horizontal hole in the stud and then the 1-3/4″ mounting hole is drilled to connect into the first hole, thus creating a path for the wires to reach the SCR (see picture).
