The cab a few streets up has also had one put on.
They added a line capacity extension to that particular cab a few months (5/6?) ago - so now it has an extension which goes to the pavement and without vents on one side.. and on the other a newly added pod with vents that looks identical to the one added to mine cab. Will have to check some of the other local cabs next time I'm out and about.
Further to this I've now attached a photo below.
You can see on the right the extension pod I thought was usually used for tie pair relief that was added a few months ago. These pods usually go to the ground and don't have vents. Then very recently it's gotten a vented pod on the left which hangs from the side of the PCP.
So having seen this and the one on mine appear at about the same time you can see why I wondered what on earth was happening. There are not the only 2 cabs which have recently sprung vented pods as I've noticed a few more in the area seem to have got them too.
but utilising existing stock, is as good a shout as any in my book.
Agreed, seems about the most logical reason to assume it was reason 2 in b*cats post.
Thanks for the info.. I guess in future we will now have to be aware that even the vented boxes may not necessarily contain electronic equipment.
I wonder if there is much of a price difference between them... probably not in the grand scheme of things.
