أنبوب بلاستيك، صندوق كهربائي

I was worried about finding the right replacement for my SC4, but this tube matches the 186B diagram perfectly and fits without any hassle. The plastic feels sturdy enough to keep my setup aligned properly.

The plastic tube is exactly the right size for the SC4 part #186B slot, so the electrical box lid sits flush again without any wobble. Took me five minutes to swap out, and the fit is snug enough that I don't worry about it shifting during use.

The part number matched the SC4 diagram exactly, so no guesswork on fitment. It’s a simple plastic tube, but it did its job holding the electrical box in place during reassembly. Glad I found the right replacement instead of rigging something.
