    Because it is attached to the case, not the optical plate.

    If you don't have 2" of headroom for it then obviously it's not an option. It just fits between my green driver and one of my PSUs. The other option is to make a table with securing straps, as I believe Danny suggested and Carl B uses.

    don't have time now to post a link.
    perform a search for a video-projector stand.
    i think is the best solution for "fast" set-up.
    anyway, the stand must be placed on a good spot, to avoid people touching the stand and knock it down.
    also at least 2 cables will go to that projector so it's a good idea to use some duct tape to secure the cables.
    maybe I'm wrong or thinking to far...
    but, as long as a piece costs 10keur, would you let it on top of a tripod made of few sticks, be it for professional use or not.
    I rather prefer the use of stacked empty light cases, already present on any event, be it huge or small.
    heya, pro's! give us some suggestions!!!

    Just a suggestion for reducing overall cost and mess... DONT USE DUCT TAPE!!

    For addressing cables, I highly suggest Electrical tape. A roll at a time its a buck a roll. At quantity, you're looking at 30cents a roll. For *short* gigs (less than a week or so) it wont leave residue, just like Gaffers tape. Gaffers tape is just like duct tape, but again wont leave residue.

    Both E-tape and gaff tape can be taped adhesive to adhesive and come apart fairly easily, compared to duct tape. If you have ever pulled up a cable that was taped down with duct tape or worse yet packing tape, you know what kind of mess can happen!

    Gaff tape is about $12-14 a roll - but I am sure anyone who has used it will praise it.

    I use gaffer tape to tape cables down to the stage to pevent trips (as you say; it comes off without leaving the cables sticky), but I use spring clamps to secure cables to the truss or tripod, they're secure and instant. The ones that I use are similar to below, but have curved jaws so the wrap right around the truss and leave a void that can take several cables.

    duct or gafa tape, not so important. i agree gaffa it's the better, if you don't want to spend money on cable crosses. , the thread is about putting a lightbox ontop of something

    not suitable for use on carpets

    I would hardly call this "a few sticks" read the spec, it can accept scaffold fittings for extra stability and is certified to carry 100kgs at 3.7m high.

    Adrian, I am merely providing a suggestion to securing cables, as you brought up in your post.

    Doc never said those were meant for taping cables down... just for using on the actual tripod.

    Neither do I Doc

    Good job! I'm sure it looks nice and is stable!

    Sandbags, however, are still my friend for anything that goes up in the air that is not flown

    EDIT: Adrian, cases work great for it too - depending of course on the height. I have cad drawings somewhere of a completely automated case specifically for stabilizing a laser projector. It basically built the laser into the case with a scissor lift. There were a few options to the way it would be secured to the ground (bypass the castors, as I felt locking castors were not sufficient).

    If there is any significant height involved, either a scaffold like tower or a flown truss (or other type of beam) is necessary IMO... Stacking road cases above maybe two or three high gets iffy... of course depending on the size of case involved and even if they are empty. At the shop we stack 1/2x1/3 pack (R&R Fiberglass style) cases four high... moving them isn't hard but it is still scary...

    The stand is quite good, for big set-ups. Will it fit on your car? What about if you have 3 projectors?
    Just curious how will you set it up on a ballroom with floor carpets, placed safe, so nobody risks to touch it and taking less possible space?
