The colors are apparently randomly distributed, as is clear from the reviews forth.
The trailers have a standard size. To remove the Pappschildes and the plastic cover of the metal trailer must OA against moisture are removed. For small pliers is very convenient.
The bending of the metal is fairly simple - if you use a pair of pliers. The removal of the font plate and the cover is also easily possible.
In the video, I still would like to point to an alternative use of the trailer for marking cables.
This box 100 is sure comes from a life or all the time - unless you want to color-code the key or / Jund devices. Then simply order a several boxes, hoping for the right color distribution.
For the price I draw from also no point for the random color.
