I use this a blanking plate between 2 power amps in a rack case to allow ventilation.

Does exactly what you'd expect. Perfect fit and looks better than just leaving a single space in the rack empty.

Because we all know, an empty rack space is like a vacuum that must be filled. better to use a blanking plate like this or you'll end up buying another rack compressor or multi effects just to fill the space. Buy this and save yourself instead!
