All Peninsula House Numbers letterbox plates come with a print out of installation instructions, and your installation template. We've also detailed them below if you're wanting to get prepared - or if your instructions have gone missing.
Gather letterbox plate, template and rods. Not included: spirit level, tape, epoxy adhesive (we recommend Loctite Easy Repair 5 Minute Epoxy), drill and 4mm bit. Brick or concrete may require a hammer drill and 4mm masonry bit.
Tape template at desired location. Use a spirit level to align template. Drill through template at marked points with a 4mm drill bit, then remove template and blow dust out of the holes.
Gently hand screw rods into pre-drilled holes on back of the letterbox plate. Avoid cross threading by ensuring the rod is pointing directly in to the hole when screwing, and not at an angle.
Apply a small amount of epoxy to the end of the exposed rods and push plate into holes. Light tapping may be required. Take care not to scratch the face. Don't install in rain. Epoxy reaches full strength in 24 hours.
To extend the life of your letterbox plate, clean it every six months or every three months in coastal areas. Use a soft cloth and a mild household detergent solution to remove dust, salt, and other deposits. Rinse gently with clean, fresh water. Dry with non-abrasive towel. Avoid abrasive pads and harsh or solvent-based cleaners.
We supply products only. We don't install, inspect sites or assess walls.
