I'm wondering if the BAW integrated lock could be used with a security cable, as shown in the video in the first post of this thread. Does the BAW integrated lock have an opening all the way through that would allow a thin security cable to be inserted? Obviously this would require a hole be drilled in the base ring where the lock fits.
I contacted BAW directly to ask this question. Their silver coloured integrated lock mechanism is not hollow, but if requested they can manufacture the device to use the brass integrated lock that is often supplied with Chinese devices (a cheap clone of the Burg Wachter ME/2). And they can drill a hole in the end of the housing where the lock fits so a security cable could be threaded through.
