The hem edge may be crimped into the hole of the mounting bracket withpliers. This will retain the mounting bracket in position as the mounting screws are attached. 2. Before positioning the diffuser in the ceiling, remove the pattern control element/adjustment vane assembly from a 1-slot diffuser, or remove the inner vane(s) from a 2- or more-slot diffuser to expose the mounting holes in the diffuser crossmember (stay).
