Installation & Compatibility Notes
Before installation, switch off power to the light circuit and ensure water is drained or the light is dry. Remove the existing screw from the light face-plate, discard old washer, and insert the new 79104800Z screw with the captive gum washer properly seated between the screw head and face plate. Tighten to manufacturer torque spec (do not overtighten). Restore power and inspect for proper light operation and watertight integrity.
Maintenance Tips
- Touch the screw and washer during annual light inspections; replace if the washer appears flattened, cracked or chemically damaged.
- If you notice leaks around the light housing or the face plate seems loose or oxidised, replacing this screw with a fresh washer may correct the issue without full housing replacement.
- Stock this small but critical part in your service kit to improve service call turnaround and reduce lighting downtime.
