  1. Hi Experts,

    I am asking from Germany and English is not my native tongue.
    So please be lenient toward me, if some of my expressions
    make you laughing. Furthermore I hope I've taken the right
    news-group as my problem is not very "scientific". If you have a
    better suggestion, please e-mail me, but I cannot access to all
    international NGs.

    I am searching for a special part, I cannot purchase locally,
    so I hope to find a supplier internationally.

    I need a window in a front panel of a stainless steel 19 inch rack.
    plate thickness = approx. 0.1 inch, glass thickness approx. = 0.2 inch
    The window size will be approx. 5 inch x 4 inch and should be
    made of a plastic material like Polycarbonate or Polyacrylate (Plexi).

    Usually people purchase such a kind of a rack directly from the
    rack supplier, with a cut-out, painted afterwards and a window
    fixed from the rear side, using glue or specially welded screws.

    In our case we are making individual boxes, and we don't know
    where to place the cut-out beforehand, so we have to cut out
    ourselves later on, and by the way spoiling the paint.

    We are now (desperately) searching for a supplier for a plastic window
    with a kind of a mounting frame, with the capabilities
    - to fix itself to the front panel
    - and cover the cutting edges,
    prepared for mounting in 19 inch rack front panels.

    If someone on the board knows any supplier please e-mail
    me the web-site of the supplier.

    Many thanks in advance

    Best regards

    Try this...

    Replace the complete front panel with a transparent plastic panel.
    Screen print the back of the panel with black or silver paint
    Do not paint where you want a window!
    You can also print lettering and company logo at the same time (print in
    reverse)

    If you have a problem with EMC - Fit a thin metal plate behind the plactic.
    Cut a slightly larger window in the metal plate so you do not see the cut
    edge.

    Have you looked at suppliers for PC modding (modifying) equipment?
    Some people like to cut holes in their PCs and stick windows in, so
    there is a market for kits. They are probably not the right size for
    you, but perhaps you could cut one in half or find out who supplies
    the shop and go straight to the manufacturer.

    Here is one supplier I found in Germany:

    Look at PRODUKTGRUPPE > Modding.

    If this is of an acrylic type window, you can try some of the large glass
    companies where you are located. Many of them will do work with acrylic type
    materials. They will cut it to your specifications. If you bring them the
    frame, they will cut it to fit.

    If there is any printing required on to the acrylic window, you can try some
    of the professional printing companies. Many of them can do a process called
    silk screening. It may be costly to do one or a few units, but in that case
    you can make a few spares at the same time.

    As for myself, I have bought a piece of acrylic or Plexiglas, and cut it
    myself. I sanded the edges with a fine abrasive to make them smooth. I then
    brought it to a local printer to have the silk screening done for the
    letters and numbers. The printer charged me according to his hour rate for
    doing the set-up.

    My comment is according to my interpretation of your question.
