Cylinder Finishes

Masterkeyed door cylinders have on average , between 24 and 48 moving components on the key side .

This means its very important to ensure the cylinder is maintained on a regular basis to ensure reliability in the future.

The best part is, it's so easy and takes just a few seconds! 

We recommend a silicone or Teflon based lubricant sprayed into the keyway with one short burst at the following intervals dependent on your environment or usage.

  • Coastal/Corrosive environment apply Monthly.
  • 75-100 key operations a day apply Monthly.
  • 50-75 operation a day, apply Quarterly.
  • Less than 50 operations a day, apply every 6 Months.

   Its really is that easy!  

However, under no circumstances use WD40*, Grease or oil.

Appropriate lubricants and cleaners are available via the architectural ironmonger that supplied the suite.
