Barbizon, Mole, B&H and many others supply the X-clip. Remember one Chicago run at one
point to get some immediately which even
led me to a un-marked production company somewhere on like the 200
block of Grand Ave. which turned out to be a video production company sleeper
cell. No name on the door, just kind of there. If I remember correctly the baby spud attached to such clamps is 1/4-20 screw thread but I might be wrong - been a few years since I bought some.
Think what Bill is refering to is a Z-Clip attachment for ceiling
track... If I remember correctly... bought some in the past and it's also a 1/4-20 stud based thing with normally some form of hook to hang a hanging household plant from it. Two versions of it, one that is like the above X-clip in a pivot that snaps in place, the other a frame that's thin one piece spring steel in snapping into place.
None of the above to hang a
Leko from if wise. The studio gear has it's uses for lighter say
Q-lite wash light type fixtures or Inkies, the home center type gear one might find in either the electrical section or the gardening area... sure could temporarially hang an Inkie type
fixture... but none something as above I would rely on for use in a lighting
grid. I'm sure Juno has clips for such stuff also as sold for architectural installs. Such fixtures underhung from a T-Track ceiling panel
grid is done in the industry be it architectural or movie lightin industry. Should one be doing it for the theater industry... probably not wise, and or ceiling lighting
track isn't optimum for hanging normal
stage lighting.
Last time I worked on a theater that had ceiling tiles, we hung a
grid slightly below it of pipe and or otherwise did booms cut
thru the ceiling tile to hang from the snow
truss ceiling. A question of hard points hung from. I think less about the cabling to it, and more about the use of something to hang the fixtures not designed for the extra loading on it as an immediate
point. Sure if doing a video shoot and light gear there is various clips on the market to hang from a T-Track.
