4 Port Fiber Optical Terminal Junction Box，Compact Size No Burr Pigtail Termination Box Fiber Optic Junction Box

This works. It's not expensive and you need to order different couplers if you can't use the SC that come with it but still a good value. The only real down side is that the mounting holes need to be smaller but that can be overcome. Other couplers can be found here and fit just fine. https://www.amazon.com/gp/product/B0965HBP34/ref=ppx_yo_dt_b_asin_title_o02_s01?ie=UTF8&th=1

While this is a metal enclosure, it is made from very thin tin-like metal. It's easy to bend & easy to damage, and the paint seems to flake easily. My unit arrived slightly damaged. It would have been nice if the junction box came with a couple of the green couplers instead of all blue, as I needed a single green coupler. Thankfully, these are easy to find and swap. At the end of the day, this junction box will work for my intended purpose. I wouldn't attempt to use this anywhere but indoors - this particular box is not sealed in any manner. In my opinion, this is over-priced. Based on it's construction, and the cheap tin, this should be priced around $10.
