Put those operable clerestory windows to energy-saving use with our 39-series clerestory extension crank. High mounted windows are excellent for capturing light while providing privacy, but they can also be “excellent” heat traps. It is now possible to vent the heat that rises to these areas as easily as opening any other window in the home.
It’s inexpensive and can easily retrofit to existing or new window installations. By simple removal of the existing crank handle and replacement with an adapter (see Hex-Bolt part) the crank will open and close any operable clerestory window. It is not necessary to replace the current operator. Remember that you will only need one clerestory crank to operate all windows at the same height.
Standard Finish for the crank is natural anodized aluminum
Adapters sold separately see part # 216 and 216
KD = Knocked Down (the crank is shipped in two parts that you have to screw together)
