How to measure your cylinderHow to measure your cylinder

How to measure your cylinder

It's important you choose the right size cylinder for your door, so it fits properly.

  • Step 1

    Open your door and measure from the centre M5 screw on the side of the door, to the edge of your existing cylinder on the inside of your door. This is the 'B' measurement. For example, this might be 40mm.
  • Step 2

    Then, measure from the centre M5 screw to the edge of your existing cylinder on the outside of your door. This is the 'A' measurement.  For example, this might be 50mm.
  • Step 3

    Put these two measurements together to get the right size - your B measurement goes first e.g. 40/50.
  • Step 4

    You can now choose your selected colour finish - Brass or Nickel.

Yale cylinder maintenance

Maintenance and care of your Yale cylinder: Yale recommend regular lubrication of your Yale cylinder locks to ensure continuous trouble free performance and operation.

  • Recommended lubricant

    We recommend using a PTFE based lubricant.
  • Apply lubricant to the key

    A small amount of lubricant should be applied to the key and then inserted into the cylinder.  
  • Rotate the key

    Rotate the key  a couple of times in line with the normal locking function.
  • Remove the key from the cylinder

    Remove the key from the cylinder and wipe away and remaining lubricant  to ensure it isn’t transferred onto other objects.
