The ViewClix 10/E & 15/E (all frames purchased after 2/13/2023) do not have the capability to be locked or secured with a laptop lock.

The previous ViewClix 15 (purchased before 2/13/2023) model is compatible with Kensington laptop locks with the Classic Kensington head.

Here is a link to a lock that will work with the ViewClix 15: https://www.amazon.com/Sendt-Notebook-Laptop-Combination-Security/dp/B008A4F8UA/ref=sr_1_15?crid=3GZKIS31P3IH4&keywords=cheap+laptop+lock&qid=1638484938&sprefix=cheap+lap%2Caps%2C239&sr=8-15

The previous ViewClix 10 model is not compatible with Kensington locks. 

You can also secure the frame by using a third-party stand or mount: https://support.viewclix.com/portal/en/kb/articles/can-i-use-a-different-stand-or-mount
