What are these extra things for?


Im putting in a radon mitigation system. I purchased an outdoor box for the switch. Included in the box are these extra things on the right. I know what the round things are for, sealing up the extra holes in the box, but what are the screws and small pieces of metal for?

the screws and small pieces of metal
They look like "ears" that are to be mounted on the back of the box and used to mount the box to a surface without compromising the waterproof/weatherproof rating by drilling holes through the body of the box.

Plugs for the unused holes in the box and clamps to hold low voltage sensor wire tight.

Even though it is a weatherproof box I would still recommend drilling a small hole on the bottom of the box. If water does get in, it can then get out.

Mounting feet that screw to the back of the box and seals for unused openings.

yes, drill a 1/8" weep hole in the bottom if mounted in a wet location.

Flip the box so the opening is facing the table top and the back of the box is facing you.

You will see on all four corners a slight hole and nub. You can place these tabs with the two holes and mount them with the screws to either of the two of the four corners and then with the other hole you put a screw etc thru and mount the box to the surface using the tabs. This gives you two points to connect the box to the wall surface (usually at opposite corners). The screws basically are self tapping. The nubs prevent the tab from swiveling while you put the screws in to secure the tab to the box. HOld the tab down against the box while tightening the screw into the tab.

Each tab has two holes. One of the holes is used to mount the tab to the back of the box and the other hole to put a screw thru to mount the box to a surface. These tabs are provided so you don't have to drill a hole in the back of the box to mount it to a surface. Notice there are no holes in the back of the box to place a screw thru to mount to something. This is why they provide those two tabs and screws.

Drilling a small hole in the box for drainage is optional but suggested. You would drill the small hole on the wall of the box facing downward so any water that happens to get into the box will drain out by gravity.

If you caulk around the box against the surface you mount it to be sure you only caulk 3/4 around. Only the sides and the top so any water that may get behind the box again can drain downward by gravity.

I found that a skim of silicone around the mating surface after the plug or fitting was installed help reduce water infiltration. But that was when the plugs were metal. I still drilled a weep hole.
