The product must be installed according to the instructions included in the product packaging and the door should be apertured according to the door “cut-out” dimensions and tolerances shown.
Prior to fitting ensure that:

  • Doors stored on site are stored in a clean dry area free from cement, lime, paint, acid etc.

During fitting of the lock ensure that:

  • No metal swarf or other contaminants enter the lock body.
  • The fixing screws do not damage the product finish.

After installation of the door ensure that:

  • The door is correctly adjusted with the correct clearances.
  • The lock engages the strike/catch plate correctly.
  • The door is protected from building fall-out such as wet plaster, mortar, paint and welding splatter.

If the door becomes contaminated:

  • Do not paint the lock body or faceplate.
  • Remove wet plaster, cement, mortar and other droppings immediately, using ample clean water and a sponge or rag, to avoid permanent staining or scratching of the product finish. If removal is delayed and scraping becomes necessary the surface finish may suffer.

Maintainance & Cleaning


Annually inspect the door to confirm that the door operates with the correct clearances, closes and opens without obstruction. Confirm that the lock bolt or beak engages easily with the strike/catch plate when the door is closed and the lever or key is turned – adjust the door if necessary.
Annually check that when the door is closed, the lock can be locked by key and by the lever.
NB : The lock assembly has been lubricated for life, and should not be disassembled by the user.

Cleaning Powder Coatings

Every six months, powder coated surfaces should be cleaned to protect the finish. However, in areas where pollutants are more prevalent, especially in coastal or industrial regions, cleaning should be carried out every two to three months.
To clean the powder coated surface:

  1. Carefully remove any loose deposits with a wet sponge.
  2. Use a soft brush (non abrasive) or cloth and a mild household detergent solution to remove dust, salt and other deposits. Do not use steel wool, scrapers, scouring liquids or powders to remove deposits as these permanently scratch the coating surface.
  3. Rinse off with clean fresh water.

Cleaning Chrome, Satin Chrome, Gold and Brass Finishes

Plated finishes are susceptible to tarnishing if they come into contact with moisture, wet paint, or water vapour.
All plated finishes should be coated with a non-abrasive furniture or car wax immediately after installation.
Plated finishes should be regularly wiped with a non-abrasive furniture or car wax, taking care not to scratch any protective finishes that are employed to protect the surface and prevent tarnishing.
