**Upon installation the entire flap must be lightly bent in order to have room to slip in (it is also highly recommended that you remove the outer hood, do not try and force the damper flap into an assembled unit) and be inserted into the exhaust vent, if the replacement flap is pushed straight in, the tabs will break!!!**
All replacement flaps are checked and properly packaged within the box for shipping. Tabs DO NOT leave here broken.
