Proper Size of Fan Base 24″-36″
In order to provide effective support and to safely hinge an exhaust fan using any Super Hinge exhaust fan hinging system, we highly recommend that you choose a model which supports anywhere from 2/3 to the entire fan base. By following the sizing guidelines, you not only ensure safe support of the thin material of the fan base, you also eliminate flexing and bending of the fan base which can compromise the seal between the bottom of the fan and the duct it is mounted to. Failure to do so greatly increases the risk of damaged fan bases, inefficient exhaust draw due to vacuum leaks, grease seepage and personal injury due to fan base or hinging failure.
