### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Allow for the extra  length occupied by the Thumbturn axis.
  

*by M***N on Reviewed in the United Kingdom on 27 September 2021*

While planning to replace a 2-key  45/40 cylinder (the 45 on the inside) with a Thumbturn model  I realised that the Thumbturn axle occupies  an extra 5mm length on the inside. So I ordered a shorter 40/40 model.Voila!The Thumbturn juts out  out of the inside of the door by just the right amount and I am a happy bunny.
