Locks

Or if I want to open the door on the inner track.




Anyway, the glass is 6 mm, the tracks 9 mm and the wall between them is 2 mm. So the minimum space possible between the doors would be 2 mm and the maximum (i.e. the current) is 8 mm, which is more than enough for an adult male to escape through.

That is quite the gap. I'd be less than impressed with it as well.

I've got several tanks with sliding doors.
I jam a quarter of a cork coaster into the rail of each door and that both sandwiches them closer together and keeps the doors from sliding
the cork coasters are easy to jam in and pull out, easy to replace and relatively inoffensive visually

I also have a plan to reduce the gap between the doors to an absolute minimum, so it should preferably be a lock or locking mechanism that doesn't need to fit between the doors. Or if it did need to fit between them, it shouldn't need more than a millimeter or two.

The dowel suggestion was taking this into account, but ultimately it's just a suggestion.
Yes at worst you may need to lift up two pieces of dowel if you want to open both, or the inside door. Any sort of lock will require some sort of unlocking prodecure to open.

Can't say I have any of those issues. I really don't care for the way the doors are designed at all. I mean they make great display enclosures but geez.. the issues. I did once have an enclosure of that basic design with 2 sliding doors and all. Looked great but i hated it. So many issues, all of them related to the sliding doors.

I simply don't have those issues with my basic glass enclosures with screen tops. The only escapes that happen or even come close to happening are because of my own absent mindedness such as forgetting to close the access or turning my back and getting distracted while a snake makes a run for it.
