Hope this helps, if there is anything else we can assist with, please just drop us a message. Kind regards, Lewis Locks Ltd **Q: What lock is this? The image looks different to the ones i have ordered before?** A: Please also note, that the Lowe & Fletcher 5851 desk lock which this listing is for, has a 23mm long nozzle (head depth) not 19mm as the description states (this is incorrect and we are in the process of rectifying this with Amazon as we would hate for customers to order the incorrect sized lock). If you have any doubts, Lewis Locks Ltd are able to provide any information required for whatever your lock requirements may be. Just send us a message. Thanks, Lewis Locks Ltd. **Q: Does the 19mm measurement refer to the nozzle length? I am assuming that the nozzle diameter is 16mm.** A: Yes you are correct the lock diameter is 16mm and the length is 19mm **Q: Will this fit a aa900 lock I need to replace please** A: No that one is not compatible. I cannot direct you to the lock you need because Amazon rules say I cannot show you our website. Sorry - I cannot help further. Are you able to send a good photo of your existing lock?
