| Preparation | The manufacturer lists the standard 4820-18 mounting plate separately from the 4820-18G alternative. Match the plate to the actual top-jamb push-side installation and head-frame/ceiling conditions. The catalogue specifies the 18G alternative for a flush ceiling, so do not substitute it for the standard plate without selecting that configuration. Confirm the matching operator template and support before fixing the plate. |
