17' Series Kitchen Drawer Secure Locks

[Disco Duck]

I'm sure there will be a thread to cover this but I have not been able to find it so I will ask again. What do you use to secure the drawers in an expanda to stop them jumping out while you are traveling?
I'm having trouble with the drawer under the cooktop. It is fairly well loaded up with crockery and glasses and likes to bounce out on bumpy roads ( we have more than enough of them in South Australia ) and cornering. We have broken a coupla cups and glasses already but being a pop top there is not really anywhere else to put them.
I'm thinking there must be a good bar system to secure the drawer but I wonder what others use, if anything?

Been racking the brain trying to recall but to no avail, throw a pic of the lock thats fitted ....................... There was something about a pin and spring in one model that was a cause as well the drawer catch getting bent so the latch wasn't catching fully, so have a look and the tab to see if its been bent, if plastic might be worn.
Is the draw a wood on wood slide or an actual rail slider, either way wood on wood could have worn allowing the drawer to drop and make for an easy release or with a slider a couple of screws could have come out or loose causing the same thing, van builders seem to love metal self tappers for timber work, so they fall out often.
Just a stab in the dark ................
