Thanh giữ ốc cho tủ rack

I have an old rack that does not have the modern square hole mounting pattern, so I needed something to make it easier to install my gear in it.  it can be a pain to have to hold the nuts by hand and get the screws started.

Uses m6 hardware, the nuts are a light press fit so that they do not fall back out.

Update 2/7/24: Added a 2u version so that there are fewer pieces in a full instillation.  This will allow for easier install too with holding/ installing the long strip adjacent to new hardware instead of having to reach around to hold it in place.
