Flat brush grommet for rack / patchkast

Flat version of my grommet. Fits the patch kast / rack that is on last picture.Mine has 312x310x618mm dimensions so for that version it is 100% proof.All you need to do is implement door seal strip with brush commonly available in action (19mm brush itself).It is this one: https://www.action.com/nl-nl/p/3202378/tochtstrip/Cut to lenght, put inside of groove and it will hold itself fine.I recommend using hefty cutters / pliers for that strip, it has harder core.Check out also the angled version on my profile.
