After I inquired about different ways of waterproof connection of underground cables, I found the cans of sleeves Friedl after a little research. Before that, I was on my way to pour the cable in the junction box with epoxy and am glad that I have chosen this solution. Even for a layman easy to install, plenty of room for cables and a truly convincing quality appearance. Long-term experience I have not, but I am quite sure that at the positive impression will not change according to the opinions of other users.
