MK Egatube boxes

[WeeBob]

I'm trying to figure out the best way to attach an MK Egatube Tee Box to a wall:

But I'm a bit baffled about the best way to do it (and Google is not helping).

The catalogue refers to "swivel lugs" but doesn't explain what they are, or how to use them.

On the back of the box, there are a couple of holes (extending from the lid screws) which I can imagine would be part of a mounting system... but nothing in the catalogue looks like it would be used for this.

i.e. Like the fixing bracket for Wiska boxes:

Is there a mystery part that I'm missing?

Thanks for reading.

Drill a hole in it?

just drill a hole in the back.

[Tricky Dicky]

If you have saddle clamps close enough to the tee box on the incoming conduits, there is no real need to fix the box to the wall, therefore no holes and the possibility of water ingress through the holes.

They're either part of the manufacturing process, or to allow boxes to be stacked on top of one another.

If you do need to fix it to the wall, drill through and use a round- or pan-head screw with a washer, or a flanged screw.

You are missing the letters EL!

Probably means external lug
