Great Electrical Protection
Crutchfield Customer Review (What's this?)
Although it has not been called to duty, the specs on this unit are very good considering its size. It is a bit of work to get it into a standard electrical box, but it does fit if you size the excess wires correctly. I'm going to use this on the rest of my wall mounted electronics.
Pros: Perfect for behind wall mounted electronics. Has very strong electrical protection ratings and helps hide wires behind the wall mounts.
Cons: Like other reviewers, this is a tight fit. The key is to cut wires to the size you need and then fit into the box. It would be easier if it had screws rather than wire nuts for connections.
