Indeed.

Couldn’t get any further from the actual topic if they tried

He has just sent me a picture and all it has on the back is vent holes in the back with no fins as such.

I'm in the process of getting an Openreach leased circuit installed.

Do you happen to know the depth of the fibre shelf they install?

If its the shelf from your photo (above the Adva box) then looks to be about the same depth as the Adva NTE itself.

It's about that depth but then the fibre tubing comes out the back.

There's a wall mounted option if you don't want a 1U splice tray or want to save the rack space.

Thanks jpm. We're just about bang on with rack space. If its around 200mm deep (like most trays) then it should be fine as there's a 40mm twin wall duct with a draw rope, that will contain the blown fibre tube 'shotgun' from the building entry point (where theres another brick sized transition box). Theres enough room behind it for a decent bend/sweep into the back (or corner) of the splice tray.
