Burying fiber in flexible conduit from house to garage

[vagrantly3893]

Hello, I am burying a fiber optic cable so I have internet in my garage. I have purchased the following flexible conduit to run the fiber optic cable inside:

Diameter of the Kabuflex 40 mm.
*Inner diameter: 32 mm.

I have dug a 20m trench 60cm deep. What I need advice on is the transition from inside to outside. I don't want to drill a hole in the external wall large enough to feed to conduit through. I assume I need a junction box and adapter on the outside of the wall that the conduit connects with?

Thanks

You can get “ends” for flexi conduit but they are usually pretty poor and pull out, easier to run the conduit straight into an adaptable box (Ty wrap or tape on inside to stop it pulling back out) and then go through back of that through the wall

Can I drill a hole in the bottom of something like this:

Yes that the sort of thing, Ty wrap is a cable tie or push conduit into box through hole and wrap tape around the end then pull back so tape prevent conduit pulling back through hole

Does the conduit rib also help prevent the conduit falling back out of the box hole?
